I totally agree, I just think this is purely posturing by Blinken. Policitally, Biden is on a tightrope here. He can't risk thumbing his nose up at Israel, and he can't risk pissing off any more young electors as you called them by being too soft on Israel. Sanctioning the ICC members would piss off a lot of those electors.

My first thought of a response to the top level post was:

(Narrator voice) They're not going to sanction shit here.

If anything, prosecuting him might even make Israel safer because this whole thing is serving as a recruitment campaign for Hamas or whatever replaces them if Israel manages to eliminate their current command structure.
