Bit of a strawman, the initial complaint wasn’t that he didn’t say some words, the initial complaint was the billions in military aid and actual physical support the administration gave Israel.
The only reason words matter is if they have any impact on reality. Israel knows the U.S is giving them a lot of leeway to commit this genocide because that’s what the administration’s actions say, hence they’re two-faced.
If they decide to stop materially supporting genocide, good. They were still wrong to do it at all, and they can’t undo that, so they’re still shit-libs, but better late than never I guess, and all those dead children will just have to stay dead.
