Right. Just when America pulls back, Europe should escalate. Awesome!

Right now Europe needs time to build. The calculus has radically changed. They need to build out in a fashion that is massive, but also both quick and quiet. This situation is too serious for rash action. Especially where victory is not guaranteed.
America is pulling back because it has lost its moral compass. Republican leadership has made it inconceivable to many Americans that you can have Win-Win situations internationally. At least that is the only explanation which explains for me what is happening.
Europe is already in this war and it is costing us money and European lives if we want or not.
No other way from stoping Putin.
