> U.S. should be on Ukraine's side for moral reasons and could also benefit from the military technology they are developing
America is too busy Smoot-Hawleying itself right now. The power moves are in European capitals. (Probably not Brussels.)
If you're in the Baltics, Poland, Finland or Sweden, Slovakia, Romania or Bulgaria, you should be upping your defence production and buying Ukrainian arms. Co-locate production in your territory and let that be used to re-arm yourself and build for Kyiv.
It's a win-win squared. You get defence kit and production expertise. Kyiv gets resources. And you get someone else to blow up against Russia, thereby increasing the time until they can mount a credible threat against you.
The U.S. should be on Ukraine's side for moral reasons and could also benefit from the military technology they are developing.
