Whether international relations are a solution to the problem or a way to provoke war is worth discussing. The Democratic Peace Theory under Liberalism holds that all democracies (or, more accurately, all liberal democracies) will not or rarely go to war with another. This theory is further explored in depth the link between democracy and peace. This paper analyzes the situation in Afghanistan, North Korea’s nuclear program and the United States intervention in the world. Finally, it is concluded that international relations theory can solve regional problems and lead to conflict and war. In other words, international relations are both parts of the problem and part of the solution to the issues in international affairs.
