@Husar: Much of what you said is circumstancial. There is real competition for resources and China is pushing its weight in the new scramble for Africa. As for the practicality of war, that has been shown to be a very changeable thing throughout history, depending on various changes in relations between society/politics/the military, which are far too complex to predict. I agree the circumstances right now make war unlikely, but so what, things change more than ever these days, only seventy years ago we had the first truly total war. Things might have reversed since then but there's no reason to assume that trend will continue.

While such measures might protect western strategic interests, I'm not convined they will spread democracy and create a lasting peace. The strength/roots of democracy lie in society, not in the political system itself. There are many social preconditions for democracy, like a strong middle class, an industrialised economy,centralised government etc. There can't be created overnight, and they weren't created overnight in South Korea either.

Of course, you could point out the state of affairs in North Korea, which was historically always one with the south, but I would argue that things have only been able to get the way they have done there because of international influence, artificially propping up the regime. Unfortunately things are now so bad you can't take away the food aid without everybody dying, but again that's because of foreign influence, hindering the natural deveopment of the state.

Having American troops running round having 'regime changes' seems superficial to me.
