The Weinberger Doctrine

While reading James Turner Johnson's Morality and Contemporary Warfare for class, I came across a mention of the Weinberger Doctrine, on page 22. Because I didn't know what it was, I did some research. In case anybody else was similarly ignorant, or just needs a refresher, I've included the doctrine below. I took it from PBS, and here's the link where I found it: http://pbs.gen.in/wgbh/pages/frontline/shows/military/force/index.html#weinbergerdoctrine

The Weinberger Doctrine limiting the committment of American combat forces:
1. Either the United States' or its close allies' vital national interests had to be at risk;
2. The war had to be fought "wholeheartedly, with the clear intention of winning";
3. We should employ decisive force in the pursuit of clearly defined political and military objectives;
4. We must constantly reassess whether the use of force is necessary and appropriate;
5. There must be a "reasonable assurance" of Congressional and public support;
6. Force should be used only as a last resort.

Additionally, in case you were curious as to the source of this doctrine, it comes from a speech Weinberger made in 1984 to the National Press Club. PBS also has a transcript of the speech, the link to which I've included below.
