In addition to what JumpCrisscross said, you seem to assume that, if the UN passed a resolution for an immediate ceasefire, that fire would actually cease. I see absolutely no reason for that assumption.
If we don’t even take the first step of trying to stop it we are complicit and the primary reason it is ongoing.
The SCs job is to secure global security and peace. The US is doing the absolute opposite.
But you're getting off track here. We were discussing the total package of US support for Israel as a driving factor in the current, grotesque horror we are all witnessing.
And it is the main driving factor. If that support were to vanish, Israel's expansionist adventures in Gaza and the West Bank would grind to a halt in very short order indeed.
