What do you mean how's it different? You've changed the entire question. I say again this is someone from a separate country sending money to the genocidal country. It's not the same at all. Arguably it's even worse.
Again though yes. How are you not getting that? It's your government. You're responsible for what your government does. It's not a feudal Lord. You voted for this. That's what democracy means. Rule of the people. The people are responsible. If you're genocidal government is committing genocide then you need to stop them. That's your job. The arrogance of thinking you should be immune to the horrible actions of your nation is amazing to me.
Also I don't know where all this imaginary pacifist Israelis opposition is coming from. Polls Have consistently shown massive support for genocidal actions. Just a little over a month ago there was a poll released that said 82% of Israelis supported the forced expulsion of all Palestinians from Gaza. Sidebar that's called genocide. They're not victims.
