As long as the Palestinians feel that Israel is an enemy….why help them at all?

Act accordingly. Let them fend for themselves. Treat them as the enemies they wish to be.

Israel orders ‘complete siege’ of Gaza, cutting off food and electricity,

Let ’em fend for themselves get their own food and water and electricity. Thousands of Palestinians will die of starvation and from lack of water, but that will simply be fewer enemies, right?

They should do the same with the West Bank as well. They can get their food and water and electricity via Jordan, if that country cares enough.
