I think visiting some cemeteries in Europe would explain why we're not so keen on waging war anymore far better than a long post written by me, Sasaki.

When is a regime bad enough that war is a better option?

How about the possiblity that Europe actually learned something from those two major conflicts that destroyed our continent and made countless Europeans, soldiers and civilians, suffer? Not so long ago, we were all at each other's throats, killing and destroying each other. Maybe, just maybe, we euro weenie pacifists afraid of policing the world by force, have been doing something right the last few decades? The mere fact that you, an American, are now talking about "Europe" and "Europeans" says a lot more than you can possibly imagine. Apparently, people who were murdering each other as a hobby not longer than 65 years ago, are, in the world outside Europe, seen as a homogeneous group.
