Had this discussion with a friend today, because the Confederation of German Trade Unions (the umbrella-organization of all German Unions), which he works for, and lots of other workers-rights and left-wing organization, along with the Alliance for Peace are having an anti-war-day on September 1st in my region with concerts and demonstrations and stuff.
And some groups (but not all) from that alliance are having a public demonstration for a ceasefire in Gaza (which is good) and in Ukraine (which is bad) where they will criticize the German military help for Ukraine and demand peace with Russia by making Ukraine cede territory to Putin.
