I was pretty much with you up to the second last sentence- but the misrepresentation of what started/drove WWI and WWII is revealing. The primacy of government in intercultural relations has often produced, and probably will continue to produce, devastatingly tragic outcomes along with developments that are more beneficial to better relations between peoples who are from my experience much more accommodating everywhere than their governments prefer or many times even allow. When we see other countries as adversaries, it is not the "people" driving it- it is the governments, theirs, ours and others, which are the problem. This is not likely to change anytime soon, especially with the "crews" we have in place in so many countries these days but hopefully we will reach a point where "We" the real people(s) can eventually tell our governments in more countries when it is time for them to stand down and get out of the way.
