Actually, he's completely justified in doing so if Israel has used weapons we've provided in violation of international law.
Following its January ruling, in March the International Court of Justice ordered Israel to
allow the free flow of humanitarian aid into Gaza. But that still hasn’t happened. Providing material support to Israel even as it carries out a war violating international orders makes us complicit, too.
U.S. aid also
may violate our own domestic laws: For example, the
Leahy Laws prohibit providing weapons or military aid to forces that commit human rights violations. The U.S. is belatedly considering
placing limits on one Israeli military battalion for its violations of human rights, but the misery in Gaza isn’t the fault of one “bad apple” battalion. It’s the express policy of a far-right government enabled by U.S. aid.
Still, there is widespread public support — and
growing support in Congress — for conditioning or withholding aid. A recent
CBS News poll found that 60 percent of Americans would prefer President Biden encourage Israel to decrease or stop military actions in Gaza. And a recent Pew poll found that among Americans aged 18-29, the largest segment
strongly opposed sending more military aid to Israel.
