This research explores the various security and post-conflict complications that are in part a result of the global proliferation of small arms — including organized crime, rebellion, civil war, and fractionalization of the state. The paper 1) defines the issue, 2) contextualizes why the issue matters, and 3) evaluates the effectiveness of policies at the international level. I define the actors in the debate, defines the solutions at regional and international levels, and draw conclusions about the effectiveness of weapons collection, destruction, disarmament, tracing, import and export control, and associated legislation. I find that serious violence-reducing measures should include: increasing the role of local law enforcement organizations capable of carrying out meaningful and region-specific legislation, tightening border controls, uniform implementation of the International Tracing Instrument, and effectively disarming and integrating former opposition groups in post-conflict societies.
