A Career in Defence and Security


The security policy landscape has undergone fundamental change since the end of the Cold War in the early 1990s. Some of the greatest challenges to peace and security are crimes which, while committed on national territory, permeate national borders and affect entire regions. At the same time, armed conflict between states using conventional military forces has become less significant. The risk to international security today comes from transnational threats, such as terrorism and organised crime.

As new criminal or terrorist networks evolve and distance themselves from the logics of territoriality and national political grievances, their goals expand across borders and their reach throughout the world become unprecedented, stemming from an increasingly interconnected international system. A threat with such disruptive global impact understandably requires a comprehensive and concerted effort by the international community in order to counter it.

In today’s world, national security is interdependent with global security and sovereign states acting alone are incapable of protecting their citizens. This represents a profound but underappreciated truth about globalization that the fate of states is inextricably linked and hinges upon mutual cooperation. One could argue that the events of 9/11 functioned as a wakeup call on that truth, a paradigm shift in the international governance of counterterrorism efforts, as we witnessed a more prominent and authoritative role of the United Nations Security Council (UNSC) and a renewed impetus in combating a threat that has become a crucial focus in national and international discourse. In other words, the perception of the threat changed radically after 9/11, leading countries to a new awareness of this transboundary issue, a characteristic that was lacking in pre-9/11 narratives on terrorism in particular but also on the whole national security strategies in general.

Multilateral and international cooperation on crime and terror is as necessary as it is difficult. For instance, to this day there is no universally accepted definition of what “terrorism” constitutes. The failure to reach an agreement within multilateral institutions and develop a consensus normative framework on the definition of the concept severely hinders chances of progress in the field of international cooperation in the future. It is not surprising to witness this deadlock. The overwhelmingly abused notion that “one man’s terrorist is another man’s freedom fighter” has served the purpose of justifying the politicization the term has suffered throughout history. One-sided understandings of the concept of terrorism often prevail in state legislations, and the lack of a legally binding definition ratified by the international community advances the political value of the term over its legal one. Therefore, the designation of a group or organization as “terrorist” by a country remains ultimately subjective, and hinges upon the alignment of interests between said groups and governments. What further complicates the prospects of multilateral cooperation is that rival countries with competitive geopolitical interests might benefit from a situation where the legality of their actions is blurred and unclear.

Ensuring successful peacekeeping and peacebuilding operations in post-conflict regions will also prove to be a challenging core task for the international community as a whole. Too often multilateral action has put too much weight into immediate military action while disregarding state-building and development strategies to protect and safeguard a secure and peaceful post conflict society. This clear tension is shifting the values, alliances, and institutions that make up the changing global order, the 21st century will be defined by security threats unconstrained by borders—from economic instability, climate change, and nuclear proliferation to conflict, poverty, terrorism and disease. The greatest test of global leadership and civil society alike, will be building partnerships and institutions for cooperation that can meet the challenge global instability and transnational threats.

Defense and security are most certainly one of the most all-encompassing career fields in the realm of international relations, with opportunities in both private and public sector, think tanks, academia, government institutions and the military, NGOs, and international organizations.
