The USA give an annual subsidy of $3bn to an independent and affluent state. Much of it is in the form of military hardware.
The policy supports the line that Israel is conducting a war on terror.
This is part of state supported military action:
Destroying the means for a population to feed themselves and earn money from food crops does not fit into my perception of a war against terrorism.
However it does support the idea that Israel wishes to systematically remove Palestinians from land and colonise it for Israeli (non Arab Jews). That reminds me of something my parents' generation fought against as part of a world war.
Such action will continue unopposed until the USA recognises that their subsidy is used to displace, starve and destroy one ethnic group.
