There is a lot of things that I dislike the US* for, but as a European, I'm really grateful that they put their bodies on the line *twice* in the previous century to bail us out, even if both cases they would be completely right to say "you had it coming"**. So, a big "Thank you" to NotDrWho's parent and all his brothers-in-arms.
*) And the same holds for my country, and for Russia, and China, Israel, Egypt, Germany etc etc. Politics are messy
**) For WOI by entering in ridiculous alliances, letting minor incidents escalate, and thinking that War would be a great way to reinvigorate the continent; for WOII by not following the US'/predisent Wilson advise and instead enforcing draconian measures on Germany (looking at France), for electing and keeping in power a maniac (looking at Germany) and for trying to placate said maniac instead of doing something about it when it would have been easier (looking at all of us)
