it's not like he's able to make a difference in Israel, while Congress is basically on a full 2 year lame duck session
what else does he have to do between now and November than get out there and campaign?
I would challenge your counterfactual. Biden's foreign policy goal last October was to prevent a regional escalation. So far... he's done that, though it's on a knife's edge. A different administration might have green lit even more from Israel. Hard to know for sure.
