The United States and Israel are set to ink on Wednesday a landmark 10-year, $38 billion military aid deal that will be a boon for U.S. arms manufacturers.

It “constitutes the single largest pledge of bilateral military assistance in U.S. history,” the State Department said in a statement.

The new pact, which runs from 2019-2028, will give Israel—already the biggest recipient of U.S. aid—an average of $3.8 billion a year, the Times of Israel reports. That’s an increase from the currently deal, expiring in 2018, which gave $3.1 billion a year.

As CNN explains, the new pact differs from the previous one in several aspects, including how it will benefit U.S. arms manufacturers:

As Reuters reports, “the agreement triggered pushback from pro-Palestinian groups, who said the U.S. shouldn’t reward Israel with unprecedented aid despite its settlement-building in the disputed West Bank. The Palestinians have demanded that construction stop before restarting peace talks, and the U.S. considers the settlements illegitimate.”

Yousef Munayyer, the executive director of the U.S. Campaign to End the Israeli Occupation, for example, told the New York Times that the U.S. is “helping the Israelis sustain the costs of the occupation we claim is unsustainable,” adding that “it is high time we address our complicity in [the occupation.]”
