I think the mess we have right now is because of many bad choices by US and allies since WW2:
1) They could reduce and rate limit lend lease to Soviet similar like they rate limited to Ukraine so buy themself more time until nuke is ready and then drop one on Dresden or Berlin (Berlin capitulated in May and they had first nuke in July so just few months later). After that probably didn't had nuke Japan. Also Poland and other eastern countries maybe wouldn't be a puppet state because Stalin lied to them and they would be under influence of US and Soviet Union would be weaker.
2) If they didn't have russian spy in their manhattan project then maybe russia wouldn't have nukes or had much much later.
3) If their didn't listen to british and US didn't overturn Mossadegh (instead of negotiating oil deal) then they wouldn't have maybe such a big mess in Iran and middle east now.
4) If the put some leash on Wall Street and their corporations then maybe they wouldn't let China to outcompete them so easily and now wouldn't have to worry about their own economical dominance.
5) If they would upfront told russian they will return nuke to Ukraine in case invasion because of broken contract commitment then they wouldn't have to worry about current mess in Europe.
6) Not much familiar with the whole history of Afganistan but still wondering what and how badly they US screwed that Afghans that were fighting with Soviet Union with aid of US turned agains them.
