Europe should forget about buying American for the future now, maybe for Ukraine only if the option even still remains but for our own militaries we need to have a strict focus on Europe made. America is a liability and it's too risky to place our trust in them now and if America wants to act this way, be isolationist, then lets hit them where it hurts; In their MIC.
Our entire armies should be European focused, European Jets only, European Tanks only, European IFVs only, etc. No American shit in sight, it would also help to boost our own military defence industries and really scale them up when all European countries are buying from each other only. Send all the American shit to Ukraine and replace it with European.
Canada can join us. No one should be buying American at this stage, the differences are negligible as well, America's thing may be slightly better than this European counterpart but Russia is significantly behind them both, so an argument on quality is ultimately irrelevant, this is about European security now and European unity, which America doesn't want to be apart of.
