> US funds and supplies Israel 2/3rd of their entire weapons supply (while they have universal healthcare)

This is misleading.

Israel’s annual budget is $270 Billion, of which $45 Billion is military. US aid is around $3.8 Billion a year.

I don't know the numbers, but you and the parent are saying different things. The US could still be supplying 2/3s of Israel's weapons while only subsidising about 10% of that supply.
