Sounds like a ceasefire to me. How else would they do this? Definitely not with any of the military tactics Israel is currently using.
Those bodies have zero power and countries that want to massacre will kill no matter what.
Israel has stockpiles of arms anyway. The war wouldn't stop just because the arms trade stopped.
