I am not and never will be a flower power sort. I don't know why you would make those inferences, they really don't make sense. Certainly not all hippies of the vietnam era bought into that crap.
War happens, it is probably a law of physics that holds true among other semi advanced species around the universe. But it certainly isn't the sort of thing that anyone who is sane should go around feeling okay about. And it feeds directly into retaliatory terrorism, which I would also infer is probably a law of physics for planet walking creatures of moderate intelligence.
As I said before, these are things that all people from all sides should be able to understand. Buying into war propaganda, or at least saying oh well, nothing I can do, THEN saying "OH MY GOD!!! I CAN'T BELIEVE THEY HATE US!!! WE'RE THE GOOD GUYS!!! It's ignorant, no matter who you are, or what your political beliefs are. Wars piss of their victims. I am not attempting to challenge anyones beliefs about which wars are good and which are bad, that is an individual opinion issue. I am merely making the point that when you or someone who associates with you, like our presidents, sets out to kill people in another country, particularly for extended periods and in with large body counts, it would be prudent to realize that it will anger people who may end up wanting you dead in exchange for their lost family members and friends.
That said, I'm not really so sure that our opinions on violence are very different. Perhaps it's just that we come to the similar conclusions, but for different reasons. That you advocate retaliatory wars and didn't mention imperialistic ventures, at least in theory suggests that we may think similarly, even if not when it boils down to specifics.
