It's complicated, I wouldn't use the historical part here before 45. Germany is since the Marshall-Plan deep in the hands of US politics. If Palestines are not allowed to demonstrate in the US, then it's not allowed in Germany.

Any critism about Israel-poltics from Germany would be attacked with antisemitism.

This conflict is highly complicated for Germany, foreign minister baerbocks abstention at the UN resolution earned hard critics from Israel, but German people approved this decision because it shows the inner conflict between pro Israel and against a genocide. It looks like both isn't possible anymore. And the USA should decide quickly, germany would follow as always.
