Granted, the US did a lot of warmongering in the middle east; I get that they wanted to retaliate after 9/11, but instead of rooting out the ones responsible directly they made up a motive (WOMD in Iraq) and did a full scale invasion there; I'm not saying Iraq was a pleasant, peaceful country or that Hussein was a nice guy, but the US invaded it under false pretenses and dragged other countries into it, eventually leading to the rise of IS and a lot of other things that I only have a superficial knowledge of.
But Europe hasn't done any of that, as far as I'm aware they've held a "live and let live" line since the fall of the USSR.
