When Trump says "America First" it ceased to be anybody's friend. Imposing Tariffs just like ,taking a moral highground is hypocrisy as the USA is not " so fair" when it goes back on $-Gold peg just like that, exports it's Inflation and weaponizes $ via Sanctions which is breach of Trust.
As regards weapons purchase Russia's are better and cheaper.US sells old generation stuff,possibly with a "kill switch".
