You miss the point.
*Of course* Germany was an expansionist, imperial power. *Of course* it was a public service to the world to stop it.
My point was Brett Knowlton was wrong when he said that weapons are there to be used in self-defense: that there are times when it is appropriate--moral even--to use weapons not in self-defense, but to make one's adversary change one's mind.
And since his most recent posts acknowledge this, I am somewhat satisfied.
I am not completely satisfied because his claim that "...I support intervention in cases where genocide is taking place..." seems to me overbroad: such a doctrine would have committed the U.S. to intervene (i) in the Ukraine in the mid-1930s, (ii) in China in the late 1950s, (iii) to have assisted the Vietnamese in their intervention in Cambodia in the late 1970s, and to intervene now (iv) in North Korea. Of these, I think that only (iii) would have been worth doing: in spite of ongoing genocide, I think intervening in the other situations would have been likely to do more harm than good.
And in case you have forgotten, I am *opposed* to NATO's course of action in the Balkans today...
