Back in 2002 or so, a friend of mine swore blind that an American had been arrested for wearing a "give whirled peas a chance" T-shirt — which is an anecdotal way of saying: are you sure you've got the full story?
I'm learning German by listening to „Langsam Gesprochene Nachrichten“ by Deutsche Welle, and it definitely looks like a lot of people are less than enthusiastic about how Israel's forces are conducting themselves in war despite the constant note that Hamas is (1) a terror organisation that (2) started this particular round by killing 1000 civilians: https://www.dw.com/en/israel-withdraws-from-gazas-devastated...
Germany is also extremely sensitive to every aspect of this due to the events of 80 years ago.
Reports I've seen from the BBC show that there are significant protests in Israel, by those who consider the war to be justified, against their own government, not only for dropping the ball by failing to prevent the initial attack, but also for driving a wedge between them and their closest allies with the conduct of the war: https://www.bbc.com/news/world-middle-east-68722308
