I'm never keen on getting into WWII-based discussions of pacifism (too many bad experiences with them in the past; also, Godwin's Law) but my general feeling is that one has to draw a distinction between fire-fighting and building-to-last, cf. friend_of_tofu's comment below. On the other hand, I'm also never keen on the assumption that opposing a problem on its own terms is either a) always a good idea or b) the Only Thing To Do, viz. the seductive romance of the TINA mindset.
