“It’s not our fight, it’s past time to let Europe fix its own messes”
You don’t like the label “isolationist”, but your belief is such.
Same attitudes that got us bombed at Pearl Harbor and NYC.
At what point would you have gone in against Nazi Germany, that is without the benefit of hindsight?
No comparison.
US has protected Europe since the end of WW2 to the extent that, with few exceptions, they spent their $$ on social programs because Uncle Sam was paying for (most of) the defence costs. Now their societies are able to afford to defend themselves (if they want to ) so let them take the lead for a change, it’s their back yard after all.
