The Senate on Wednesday blocked two resolutions that would have stopped the sale of about $450 million in bombs and bulldozers to Israel, as President Donald Trump's fellow Republicans rallied behind his support for the Jewish state.

But support for the resolutions from ‌a large majority of the 47-member Senate Democrat caucus underscored growing frustration within that party about ​the effect on civilians from Israeli strikes on Gaza, Lebanon and Iran.

A decadeslong tradition of strong bipartisan support for Israel in Congress means resolutions to stop weapons sales ⁠are unlikely to pass, but backers hope raising the issue will encourage Israel's government and U.S. ​administrations to do more to protect civilians.

Supporters of the sales said Israel is an important ally to whom ⁠the United States should sell military equipment.

Sen. Bernie Sanders, I-Vt., who caucuses with Democrats, forced votes on the resolutions, saying the sales violate criteria for foreign assistance in the Foreign Assistance Act and the Arms Export Control Act.

The first ‌resolution would have prohibited the $295 million sale of D9R and D9T Caterpillar bulldozers, parts and other support. ​The vote was ‌59-40 against advancing the measure.

Seven Democrats voted with every Republican against advancing the resolution. Sen. Cynthia ‌Lummis, R-Wyo., did not vote.

The second resolution would have prohibited the $151.8 million sale of 12,000 BLU-110A/B general purpose 1,000-pound "dumb" bombs and related logistics and technical support services. Eleven Democrats joined every Republican to block ⁠the measure by a 63-36 vote. Sen. Thom ‌Tillis, R-N.C., did not ⁠vote.

"The United States must use the leverage we have – tens of billions in arms and military aid – to demand that Israel ends these atrocities," ‌Sanders said, urging support for the resolutions.

Israel said it does not intentionally target civilians, and that its strikes are intended to neutralize terrorist and military infrastructure. Wednesday's vote showed an uptick in support for efforts to limit military sales ‌to Israel. ​In July, two resolutions that would have ‌blocked arms sales in response to civilian casualties in Gaza were blocked in the Senate.

Also introduced by Sanders, they failed by 73-24 and 70-27 in the ​100-member chamber. The Trump administration bypassed the normal congressional review of military sales early in the U.S.-Israeli conflict against Iran, saying there was an emergency that made it necessary to immediately transfer the weapons.
