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.
