Ironically, the same people who complain about "slippery slopes" become the same people who bemoan the fact that American, Chinese, Russian, and even Vietnamese [0][1] intelligence operate with de facto impunity in Germany and the EU.
Europeans can no longer afford to be the idealists that they were in the 2000s. Every country is runnng influence ops across Europe to a degree that hasn't been seen since the Cold War.
That said, as an American, it's fine for me if Germans and Europeans remain naive. An allied Europe is good, but a naive but controlled Europe is equally as good. For every Atlanticist, we have people who can push our interests in an illiberal manner like Dominik Andrzejczuk.

Always the arguments of the enemies of freedom and dignity - they are fanciful ideals, not necessities and the whole point, and the foundations of the freeest, most secure, most prosperous societies in history. Maybe the rest of Europe wants to live more like Russia?
