The U.S. gives more than $3 billion in unconditional military aid to Israel every single year — more than any other country receives, by far.

In fact, more than half of U.S. foreign military financing goes to Israel, a country roughly the size of New Jersey.

The vast majority of the Senate, however, thinks $3.1 billion per year isn’t enough.

More than four-fifths of the U.S. Senate signed a letter pressuring President Obama to boost military aid to Israel, Reuters reported Monday.

A whopping 83 of the 100 senators signed the letter, including 51 (94 percent) of the 54 Republicans and 32 (73 percent) of the 44 Democrats.

Presidential candidate Bernie Sanders, one of the Senate’s two independents, did not sign the letter.

Presidential candidate Ted Cruz, who is struggling with front-runner Donal Trump for the Republican nomination, did endorse it.

The bipartisan initiative was led by Republican Lindsey Graham and Democrat Chris Coons. Their letter calls on Obama to quickly reach an agreement on a military aid package for Israel.

The letter does not specify by how much exactly U.S. military aid should be increased. The Israeli government wants $4 billion to $4.5 billion, yet some U.S. officials have proposed $3.7 billion.

Sanders, one of the just 17 senators who did not sign the letter, has broken with Democratic Party dogma and criticized Israel for its atrocities in Gaza and its oppression of the Palestinians.

The self-declared democratic socialist has insisted in interviews and a presidential debate that Israel’s attacks in its summer 2014 war in Gaza were indiscriminate and disproportionate.

Numerous reports by the United Nations, leading human rights organizations and even the U.S. State Department acknowledge that what Sanders has said is correct.

According to the U.N., the Israeli military killed more than 2,250 Palestinians, roughly two-thirds of whom were civilians, including at least 550 children, in its 51-day attack on the densely populated Gaza Strip, bombing civilian homes, hospitals, schools, places of worship and shelters for displaced people.

Sanders, who also happens to be the first Jewish major presidential candidate, has made a critical break with pro-Israel bias. He has called for the U.S. “to treat the Palestinian people with respect and dignity” and “to work together to help the Palestinian people.”

The senators’ letter, which was obtained by Reuters, asserts “we stand ready to support a substantially enhanced new long-term agreement to help provide Israel the resources it requires to defend itself and preserve its qualitative military edge.”
