This was kind of inevitable. Even before Trump gave a shock to the Eurocrats, Europe and the US were drifting apart. Even the honeymoon period of US-Europe relations under Obama were just delaying the inevitable. Without the threat of the Soviet Union, there is no major international rival to keep the US and EU joined together. Russia just isn't scary enough to the EU powers for them to want to give the US as much leeway as they did during the Cold War. People are laughing at them up thread for not even spending 2% on defense but it's not really needed. They've got enough of a deterrent even without the US to keep the Russians from doing anything but play proxy warrior in Ukraine and the Caucasus.
At the end of the day, US and EU have different interests which is going to lead to a fundamental split in how they handle international affairs.
