Yes, but he said that in the context of buying American products. He wanted the American economy to benefit from arms sales, not a more independent Europe.
EU is being threatened with tariffs because we’re not buying „enough” things from the US, including among others arms. The „suggestion” has always been to spend that money in the USA.
This isn’t “Europe” pushing for a war, that’s solely Russia. That’s also why this policy reversal is so shocking: until recently, pretty much everyone accepted the post-WWII consensus that the United States helping to stabilize Europe was better for everyone. Trump throwing in with Russia is not only a betrayal of our allies but also dramatically increasing the risk of war since it tells Russia and anyone else so inclined that wars of aggression are viable as long as you make it financially rewarding for him.
No, it’s Europe. Ukraine decided not to join the EU and the West supported a coup via the Maidan Revolution. The extent of that support? I don’t know, but at the very least we were verbally encouraging the violent overthrow of their government.
