I don’t see that happening; like I said I think Israel gets their weapons no matter what they do with this generation of leaders. Even if Biden has the legal authority, he has made it clear he does not have the inclination.
I think the comp here is Republicans with Trump; they will furrow their brows and say that “if he does X it will be too far”, then immediately fall in line after X happens.
When the people who are now, say, 35 or 40 are in office, things might be different.
