NAFTA has bolstered cross-continental cooperation.  By expanding their free trade regions to the entire continent, Canada, the US, and Mexico have demonstrated the plausibility of greater international cooperation. Although NAFTA is not on the scale of the EU, it similarly demonstrates the ability of nations to work together for mutual benefit, thereby increasing international cooperation. NAFTA helps create a secure North American continent where none of the states need be worried about the other members in much the same way as the European Union does in Europe. Competition and potentially wars are prevented through greater trade integration as is shown by European integration since the second world war.
