ABSTRACT
This study focused on International Security and Global Terrorism in the 21st Century. The aims of the study were to explain world problems of international security and terrorism, examine the patterns and trends of world terrorism and their effects on international peace, evaluate the efficacy of counterterrorism measures and policies pursued by international organisations, regional bodies and states and recommend policies and strategies to reduce world terrorism and promote world peace. The research was carried out using a qualitative research design, informed by an extensive literature review of peer-reviewed journals, policy documents and official reports, which allows a comprehensive analysis. Findings showed that terrorism is an ongoing and evolving global threat, with hotspots in the Middle East, Africa, and South Asia, and the rise of groups such as ISIS, Boko Haram, and Al-Shabaab, who are using weak governance, transnational networks, cyber capabilities, and financing to continue to operate. The terrorist threat has been further compounded by globalisation and technological change, which have eroded the boundaries of national sovereignty and international security. Counter Terrorism Strategies in this case UN Global Counter Terrorism Strategy, as well as in the case of the United States and UK, France, Nigeria, and Afghanistan and Pakistan, or at a regional level, the African Union, European Union, and the Association of South East Asian Nations, as well as national strategies, especially in the United States, UK, France, Nigeria, Afghanistan, and Pakistan, have been reasonably successful in intelligence sharing, operational coordination, and legislative frameworks but there are also limitations, including the gaps in implementation, unintended consequences to society, and the ability of terrorists to adapt. The study calls for expanded multilateral intelligence cooperation, the more effective combination of socio-economic deradicalization programmes, the reinforcement of regulatory frameworks against cyberterrorism and terrorism financing, and human rights to be made a priority in security operations to guarantee sustainable and effective responses to global terrorism.

1.1 Background of the Study
The most notable features of the 21st century are the changes in the situation of international security with the emergence of international terrorism as a key threat to peace and order. Terrorism has developed from local insurgencies to being a global problem that threatens the sovereignty of states and destabilises societies and the international order. According to Savic (2005), the terrorism is increasingly blurring the domestic and the international security which has created new vulnerabilities both for the states and non-state actors. In this regard, Ervine (2020) points out that terrorism is not just a national security concern but a multidimensional problem that has economic, political and humanitarian implications for the global community. This dynamic interdependence goes further to explain why the nature of terrorism needs to be understood if it is to be regarded as a permanent feature of international security in the postmodern world.
Terrorism was (and is now) a major security concern around the world and the post 9/11 environment was a watershed moment for its transformation into a global security problem that would lead to wars, global alliances, and increased global surveillance. Rogers (2022) argues that discourses of security in a globalising context were transformed by the so-called 'War on Terror', which provided a new justification for legitimising new practices of counterterrorism that changed state priorities. Calculating the same, Smiljanic (2025) explains that the international war on terror unmasked the character of military based counter terrorisms by depicting its insufficiency in handling the challenges of the unilateral responses. These debates suggest that while terrorism resulted in unprecedented international coordination it also created new tensions between security and human rights-for the long-term. In this context Rosa (2024) considers that terrorism has become a type of asymmetric conflict and has turned into a new form of political communication, founded on the interdependency which is global in nature.
The twenty-first century has seen the further militarisation of terrorism with the formation of transnational organisations such as Al-Qaeda, Isis and Boko-Haram which are not hampered by geographical boundaries in their ideological, religious and political pursuits. Elemanya (2023) stated that Islamic State of Iraq and Syria (ISIS) is the new face of the global jihadism that has taken advantage of the modern technology to disseminate the ideology as well as recruiting people in the continent. Also, Gyamfi (2020) has stated that in Africa, non-state actors such as Boko Haram and Al-Shabaab, destabilised entire regions of the continent, leading to humanitarian crises and strangling development. These findings give credence to the idea that open borders, new technology and weak governance structures contribute to today's terrorism. As taken from Iskakov 2025, new forms of terrorism and extremism have become even more flexible as they adapt to the use of ungoverned spaces, and the use of global networks to sustain themselves in their operations.
Furthermore, terrorism has become easier to spread around the world and even more devastating to international security since the advent of globalisation. According to Calleja (2021), the practices of global mobility, money laundering, and digitalisation are transnational terrorism due to the circumvention of the state. Broeders et al (2021), confirms this by citing that cyberterrorism has become a new frontier in the global security arena, where extremist actors are taking advantage of information systems, in which they are exploiting cyber spaces to attack the weak points in the physical world. Additionally, Sebastian (2020) argues that cyberterrorism is an insurmountable threat because it can lead to economic and government destabilisation as well as spread of propaganda. In the present context it is possible to notice that the terrorism of the 21st of century is no longer isolated from the physical violence, but has spread into the digital environment, growing in its extension and the impact on international systems.
The subject has also been broached in terms of international security, as subjects such as bad governance and fragile states are discussed as breeding grounds for terrorism. As Chitadze (2022) points out, places of political instability and poor governance are usually fertile breeding ground for extremist groups. For instance, Rath (2023), shows the reason for the low stability of the governance structures in Pakistan which contributed to the resilience of Taliban and Al-Qaeda networks. Also, according to Gyamfi (2020), the African context of fragile states alongside porous borders makes it possible for terrorist groups to use such states as safe havens. The arguments illustrate the cyclic nature of the linkages between fragility and terrorism, where fragility is the breeding ground for radicalisation while terrorism is one of the elements contributing to fragility. Terrorism is more often a geopolitical instrument which is applied for the purposes of pursuing larger strategic ends in international relations, according to Izoria (2024).
The proliferation of weapons of mass destruction (WMDs) have added to the confusion with terrorist organisations wanting chemical, biological and radiological capabilities. According to Pradhan (2022), the acquisition of WMDs is tied to the process of terrorism, which leads to the escalation of the catastrophic nature of an attack, and, in turn, the need of counterterrorism is heightened at the global level. Dinca and Dinca (2021) also explain that prevention of such catastrophes is among the priorities of Euro-Atlantic security structures because non-proliferation and intelligence sharing are major security strategies. Meanwhile the intersection between terrorism and other global risks such as climate change is highlighted as bridging the gap between security discourses and other non-traditional threats (McDonald 2024). These arguments reveal that terrorism is no longer taken as a separate phenomenon, but has become more embedded in the broader discipline of international security issues.
The reactions of the international community to terrorism has led to a plethora of scholarly debate on the efficacy of multilateralism and unilateralism. Martini (2021) conclude that United Nations has played key role in normative development of global counterterrorism despite the fact that there are still gaps in implementation. Nwala (2023) also notes that international diplomacy is very important in implementing co-operation and intelligence sharing where there is a lack of adequate capacity for regional organisations. In the light of the aforementioned findings, Javadi (2023) argues in favour of the way in which the European Union has become an international counter terrorism actor using a blend of legal, security and development approaches. While questions of coordination, legitimacy and sovereignty are still debated, they do nonetheless demonstrate the changing role of international organizations in creating international responses to security issues.
However, multilateral action, regional and national experience all demonstrate different levels of success in combating terrorism. Gyamfi (2020) argues that regional African organisations such as the African Union have been plagued by the disease of lack of capacity that have undermined the capacity for counterterrorism. Likewise, in a similar vein, Zieba (2022) reminds of the fact that the French state has issued certain national security strategies that are related to terrorism attacks, on the basis of the specific pressures to which European states are subjected. Nwala (2023) argues that there is still a need for diplomacy to help manage the convergent and divergent interests of nations and the development of an integrated strategy. We have learnt that because of the international nature of terrorist attacks, there is need for agile responses which combine national resilience with international cooperation. Andric and Kovac (2021) state that modern terrorism still keeps evolving and eludes even the most contemporary techniques to combat it.
Terrorism is an intimately connected problem with international security in the 21st century as globalisation, technological developments and geopolitical competition spur groups such as al-Qaeda to invent new methods of striking and damaging the world. As argued in Guntay (2020), constructivist approach to terrorism views terrorism not only as a material threat but as a social construct which has been manipulated by the narratives, identities and perception of terrorist regime. Further on Cole (2022) asserts that terrorism is a theatrical creation that is designed to be used for the manipulation of political agendas and public opinion. Taken together, the information reveals the critical need for sophisticated analyses that look beyond the simple study of military responses to terrorism and that consider the socio-political context in all its complexity. Thus, the relationship between terrorism and international security is a rich subject for further professional academic research, for instance on the significance of international co-operation and risk management (international relations) (Abbas and Xu, 2024) to counter the dynamic security challenge that terrorism poses. This understanding makes terrorism a unique problem of global politics, and a long-term threat to the adaptation mechanism of international security structures.

2.1 Statement of the Problem
The continued presence of terrorism in the 21st century is one of the most critical challenges to world peace, stability and development. Despite decades of counterterrorism efforts, terrorist groups continue to destabilize fragile states, target civilians and undermine international cooperation. According to Rosa (2024) an activity that had started as a violence characterizes terrorism on a local level has become a global phenomenon utilizing technological innovations, financial networks, and deficient governance structures. Mike Elemanya (2023) adds to this by stating that transnational organizations such as ISIS and Boko Haram have successfully used globalization to recruit members and commit acts of violence which in turn has increased their influence on a global scale. The ideal situation is one where international security systems supported by multilateral cooperation and national resilience manage to anticipate, deter and counteract the threats of terrorists. However, the truth is a growing disconnect between the range of the evolution of terrorism, and the efficacy of current responses.
The current scenario shows that international, regional and national strategies have been only partially successful in countering terrorism, and often with unintended results. Martini (2021) points out that the United Nation's Global Counter-Terrorism Strategy has offered significant normative underpinnings, however, it is not being effectively implemented in many states. Similarly, Smiljanic (2025), identified the military-oriented approaches to global war on terror, which decreased terrorist nests but did not deal with the rooting complains, and resulted in splinter groups. At the regional level, Gyamfi (2020) observed that African security institutions are structurally and resource wise weak hence the states are exposed to difference extremist networks. In essence, counterterrorism measures should aim to go to the source root, to promote socio-economic development and good governance, while eliminating the current threat. The continued nature of radicalisation, cyberterrorism and transnational networks suggests that the international response is reactive and not proactive and this is the problem this research is attempting to explore.
An important gap in scholarship and practice is the piecemeal evaluation of counterterrorism strategies and their efficacy over a long-term. While scholars like Calleja (2021) and Javadi (2023) underline the importance of multilateralism, there is still not enough analysis on how the different approaches interact and whether they actually contribute to a better international peace and stability. In addition, Iskakov 2025 highlights the emergence of new types of terrorism, such as extremism linked to digital platforms, which are not yet well thought out in the standard academic and policy discourse. This research fills these gaps by looking at terrorism not just as a threat in the here and now, but as a multidimensional security issue that needs to be responded to in holistic ways. By doing so, the study intends to make a contribution to the debate on closing the gap between the needs of the policy frameworks and the practical realities and, hence, to provide ideas on how better to establish international security in the 21st century.

CHAPTER FOUR:EFFECTIVENESS OF COUNTERTERRORISM STRATEGIES AND POLICIES
MAJOR FINDINGS (Preview)
The analysis results were presented in tables. Based on the results obtained from the analysis, the following findings are made:

i. The study found that national counterterrorism strategies have played a significant role in addressing global terrorism in the 21st century, as evidenced by the adoption of legislative measures, military operations, intelligence sharing, and homeland security policies by countries such as the United States, the United Kingdom, France, Nigeria, Afghanistan, and Pakistan. These strategies have contributed to disrupting terrorist networks, strengthening national security institutions, and improving cooperation among security agencies, although challenges such as inadequate funding, weak governance, and human rights concerns remain.

ii. The study found that international, regional, and national counterterrorism efforts have achieved notable successes in combating global terrorism in the 21st century, as evidenced by improved intelligence coordination, the disruption of terrorist financing, the recovery of territories previously controlled by terrorist groups, enhanced border security, and the implementation of deradicalisation and rehabilitation programmes. These achievements demonstrate that integrated military, legal, intelligence, and socio-economic strategies can contribute to reducing terrorist activities and strengthening international security.

iii. The study found that counterterrorism strategies have significant limitations and unintended consequences that undermine their overall effectiveness, as evidenced by the continued adaptation of terrorist organisations, inadequate coordination among international actors, civilian casualties, displacement, human rights violations, and the persistence of socio-economic conditions that encourage radicalisation. These challenges indicate that an excessive reliance on military operations and surveillance, without addressing the underlying causes of terrorism, may provide only temporary solutions to terrorist threats.
