It doesn't sound bad for new world country in 19th century.Pre 1900's style isolationism basically we just tell and force anyone from the old world to fuck off from North and South America. Doesn't sound so bad to me tbh.
Unfortunately we can't shove them into a time machine to send them there, and USA is a very different country with a very different position in the world now.
Also even in that obsolete view, we both know that China is the elephant in the room and is absolutely not going to fuck off from Americas willingly (look up how they are getting their influence into SA), and these "geniuses" are absolutely not focusing on that either, just on Russia being bled in Ukraine as if that was a bad thing.
There is also huge irony in that logic. The biggest problem with Afghanistan was that despite massive resources pumped into it, the whole project turned out to be a house of cards in the end.Horseshoe theory of politics keeps rearing it's ugly heads.
Ukraine is paying the price for Biden's shit-tastic withdrawal from A-stan because of how it burned so many on foreign policy, while the stolen election means some simply will not accept that someone can be ok on domestic issues, but have massive blindspots on foreign affairs.
Meanwhile Ukraine is doing some quite impressive things for a fraction of the same resources... and the malcontents are complaining about it more than they did about Afghanistan, where's the fucking logic?
