The purpose of this article is not to address every aspect of the change taking place in NATO but rather to focus on the enlargement and globalization policy of NATO, which is one of the more important dimensions of the change it has undergone. NATO enlargement policies not only reunite a fragmented Europe that won its independence after the collapse of the Soviet Union and strengthen European security, but also create an environment of joint action against the threats listed above by encouraging partnerships, cooperation and dialogue in the areas of comprehensive peace and security with countries outside of Europe.
