The German authorities claim they have proof of the connection between the IZH and Hezbollah. If they do have the proof, which they now under obligation to provide of course, it is not politics and Islamophobia, it is doing what the law requires.
Now you may think the law should require doing similar things to such organizations aiding Israel. I wouldn’t disagree. But that doesn’t mean you let other organizations that aid a different group that commits atrocities and want a theocracy just because they’re fighting Israel out of some sense of fairness.
