First off, let's keep it civil. Invectives are not becoming in any discussion.
Now, as for your statements. My statement about vengeance not being a factor applies only to the question posed...that of POSSIBLE US activities in "Iraq, Iran or North Corea[sic]." Was there an element of vengeance in the U.S. actions against the Taliban in Afghanistan? OF COURSE! Who could deny otherwise? But against other countries...I doubt it. That is for the security of America, no matter what action is taken.
It should be remembered, of course, that the U.S. has not publicly stated any plan to attack ANY OTHER COUNTRY! Simply naming countries as part of an 'Axis of Evil' is not a prelude to military action against them. What you see as a nation of "overemotional, immature, xenophobic" people, I see as a nation of passionate, realistic, concerned and dedicated people. I am not just 'anyone from the U.S.' as I, like many Americans, live abroad. Nor is your opinion of Americans being insular accurate. Naturally, we are concerned about ourselves...indeed, it behooves Limeys to be MORE concerned about the state of their own "union" (Northern Ireland, railway inadequacies, failing NHS, racial tenions as evidence by last summer of riots) than to criticize the U.S. for taking care of IT's citizens, as it is doing, with overwhelming support from the people it was elected to serve and represent.
As for American Imperialism...again, a sign of the U.S. taking care of it's citizens. Of course, I must say, that if the U.S. doesn't act internationally, it will be seen as isolationist. By acting, it is seen as imperialist. When you are a wold superpower, the only one at the time, any action will be criticized by some nation abroad. (continued...)
