Mikel, I note from your age and location that you may have certain knowledge of Eastern European things of more recent date, but you can't know about the horrors and scars that many Americans suffered as a consequence of the US Imperialistic/Anti-Communist BS that led to Viet Nam. I don't know what the numbers are in respect of how many young Americans of my generation got shipped off over there and came back ruined for life, but I know that probably every high-school graduating class in the US for ten years or so lost members that way.
I dated a guy for several years a long time ago who was so damaged by his experiences that for the rest of his life, he was haunted and unable to find peace. He had recordings of battles and firefights and ammo dump explosions that he would listen to over and over and over again because so many of his friends died and he could not deal with the fact that he survived. He died in Spring 2010, rather too young IMO, after a lifetime of torment. I knew him. And nearly everyone from my generation knew someone like him or were, themselves, in the same situation.
Just so you know, your supposedly "innocent" questions are similar to an American asking a Polish person "Gee, what is up with you Poles finding that you are on the same page about the old Communist regime and how some of your family and friends disappeared into some political prison? Are you desperate for friends because you are friendly with someone who has the same view of those times?" That would be rather offensive, now wouldn't it?
