Ukraine
I believe rolling their economy into the Euro would immediately allow for serious foreign investment. Economically it's like hitting Powerball.
The fact is, the only time this war hasn't been in Ukraine's favor - despite incredible odds- is when we slow walked our aid. Shame on us that we let people die for politics.
But now, they are striking inside Russia and F-16's are about to enter theater.
The brain drain Russia has suffered from, self inflicted no less, is one major reason they aren't adapting imo. All of their best and brightest leave or fall out of windows.
Ukraine is coming up with modern warfare on the fly. Their drone army is getting to be a problem Russia can't handle. And while Ukraine is now effectively sinking ships without a traditional navy, Russia is pulling crap out of mothball.
