this is simplistic and badly flawed sequencing, my hope is biden does much better soon.

First : Hamas terrorist attack...they have no nukes, but biden sends military aid to a wealthy state to conduct war on one of the poorest. The kibbutz attack is on a mass scale, for which Israel seems completely unaccountable despite their supreme surveillance state, and u.s. money and intel.

Second : Israel anti-terrorist response planned. ok, par.

Third : turns out Israel has no 'plan', just mass scale warfare which becomes civilian genocide. send people to fake safezones and cut basic goods. now there are ~20X relative to Israeli civilians killed, probably aiming for 100X in Gaza.
Sure, i understand there is not much sympathy for 20k dead children and women in Gaza, but among those also killed :
-American and european citizens
-Aid workers
-Israeli Hostages
-IDF's own soldiers
in every instance, there were excuses on 'Hamas' being in the area for the strikes. GMAFB, its the actual GAZA strategy!

this is where it gets critical and biden needs to apply some bayesian priors regarding BiBi's ploys, and stop all military aid. because this is where all further israeli aggression (and u.s. complicity) is seen in the context of genocide.

Fouth : NOW we get to the non-gaza escalation by israel, and with a nuclear power. if BiBi can drag america into this, its a career saving move.

so far, Biden and GOP want to keep the military money coming. and join whatever escalation occurs.
out of all the things for Biden to agree on with MAGA, this is most repulsive to settle on.
(ok, maybe appeasing putin would be worse, but ukraine has a much lower civilian casualty rate than Gaza, despite the russia war being ~3 yrs longer)
