The North Atlantic Treaty Organization was founded with a single mission — to thwart Soviet expansionism in Eastern Europe. In 1991, the Soviet Union fell, but the mission of NATO stayed alive, in the evolved form of maintaining a union of defense for Europe and specifically protecting the sovereignty of the Baltic states, only recently freed from the iron grasp of Soviet communism.

That said, NATO has to change. Specifically, Turkey has got to go, and it should be replaced by Georgia and Ukraine.
