Most of this represents what the US has sold Israel, not given and the money gets plowed back into the US economy generating jobs for US citizens. Israel isn’t interested in the money, just the defensive weapons. It’s you who are obsessed with yellow substances.
In contrast money given to UNRWA is a dead loss, generates terrorism, pays salaries to Hamas and builds dependency and helplessness rather than self reliance. UNRWA has no business continuing its operations in Lebanon, Syria, Jordan or the West Bank and should be quickly phased out in Gaza.
Since “Palestinians” claim to be Canaanites or former Jews you should conclude that they are fake Arabs. So why would any real Arab support them?
