Saying you support funding Israel's "defensive weapons" while opposing sending it "offensive weapons" is as nonsensical as saying you would never give a mass shooter guns and ammunition, but you would give him body armor to keep him safe from the police. You're helping him commit mass murder just as much as you would be if you gave him guns and ammo. Kings didn't arm their knights with shields and armor so that they could live long and fulfilling lives, they did it so the knights would live long enough to kill the people the kings wanted killed.
