Professor Sean Kay is an insightful commenter on issues of international affairs.
Here is a short OpEd on NATO as a fighting alliance against Libya. It is useful.
One thing to keep in mind, since the media either can't or won't.—The Supreme Allied Commander Europe (SACEUR) is not "the" military commander of NATO. There is none. He is one of two Supreme Allied Commanders and some odds and ends, such as the Canada-US Regional Planning Group (CUSRPG). Above SACEUR is the Military Committee (MC) and then, above them the North Atlantic Council (NAC).
