Another weird thing to me, as a foreigner in the US, is the fascination people have for the "troops".
If we all just say "Thank you!!" over and over again, we are absolved.
After the first Gulf War, there was a deliberate effort to thank the troops when they got home, which has persisted after 9/11.
