You’re right. All of those things are happening, and they’re despicable. The Israeli people should be marching in the streets, and Netanyahu should be tried as a war criminal.
I don’t live in Israel. And in any event, we’re talking about American domestic policy. The Israel state is an evil institution–like a lot of states–but the US interest in that part of the world means that the US is going to continue to give Israel its full-throated support, and it doesn’t really matter which party is in control of the US government. That one party is using that support to attack the other is just political theater, and everyone who studies global politics knows it.
Godwin’s maxim notwithstanding, the mention of Hitler and Stalin is actually a decent example: You realize Stalin was the US’s ally in World War II, don’t you? Sometimes nations don’t get to choose desirable company. The US’s reasons for supporting Israel may not be noble, but they’re rational. More importantly, what’s the alternative you’d prefer? The US should carpet bomb Israeli cities? let Russia have the Middle East (e.g., Syria)? or maybe just send a strongly worded letter? There isn’t a more humanitarian alternative that doesn’t have worse geopolitical consequences.
