Like, if you look back at the times the US has been in these sort of issues these are the things that dragged the country out of those "funks" right/wrong better/worse:
- WWII. Primarily Pearl Harbor. Galvanized the country and almost immediately you didn't hear anything about isolationism at that stage.
- "Miracle on Ice" game. It helped the states AND it helped other countries too. An example, my mom was living in Osaka at the time after spending a brief year at school in Australia. Japan, being right next to Korea, China, and Russia felt the world was very much sliding to them. Then the hockey game happened where a pack of US College kids defeated essentially pro players and even in Japan there was a sense of "the Soviets can be beaten".
- 9/11. Christ, 9/11 made people line up in droves to support a government act that removed a ton of our rights (Patriot Act)
- The DEVGRU assault on OBL and killing him. Fuck, look at the reaction at the Phillies game when it happened:
