Despite Israeli bombardment that has brought Gaza to the brink of a humanitarian meltdown, U.S. President Joe Biden is facing little pressure at home to rein in Israel's military retaliation for an unprecedented attack by Palestinian Hamas militants.

Biden appears to have given Israeli Prime Minister Benjamin Netanyahu a free hand, for now, to press his war against Hamas, though a threatened ground offensive — with the likelihood of a higher civilian death toll — could force the president to rethink that approach.

As Biden vows rock-solid support for Israel, he has only faced scattered protest from the left wing of the Democratic Party over his acquiescence to Israel's tough crackdown in the crowded coastal strip.
