Traditionally the US turned from ally to bully in a predictable manner though. Ally with the Soviet Union, expect hostility, even if your previous right-leaning government had been their best buddies. Invade another country the US also regarded as a regional ally and oil supplier and you might not last long.
The switch to verbally attacking Ukraine and the rest of Europe whilst fellating Putin is an altogether different one, and one much more damaging to US soft power than its past belligerence.
