In writing an essay on this topic, you will need to talk about the wide range of current threats to national security. In order to succeed in this assignment, you might want to break it down into several sections:
- Introduction: Your main thesis should center around the fact that it is much harder to defend against a wide variety of threats from multiple types of entities than a single known threat.
- Transition: You then should have a transition paragraph in which you discuss some of the major types of security hazards of the post-Cold War era. The main body of your essay should address each type of threat in a separate section.
- Rogue States: You might begin by talking about rogue states, especially North Korea, and how by being outside the framework of international law and diplomacy they are a potential threat to US security.
- Russia: Putin's Russia may be no less dangerous than the Soviet Union as it still has a nuclear arsenal and is moving towards a rhetoric of extreme nationalism and xenophobia.
- China: Here you might discuss the simmering conflicts in the South China Sea and the Nine-Dashed Line territorial claims of China.
- Failed States: The next major security threat you might discuss are the failed states such as Syria, Libya, Somalia and Yemen and associated fragile states and discuss how they destabilize regions and increase the threat of terrorism and refugee crises.
- Terrorism and Cyberterrorism: In this section you would discuss how modern technology allows a relatively small group of people to pose major threats to national security by acts of terrorism and cyberterrorism.
- Conclusion: You should argue that the sheer variety of current threats makes for a greater national security risk than did the better understood and more limited threats of the Cold War.
