"Zehut" party head former MK Moshe Feiglin came out against the weapons deal signed by US President Donald Trump with Saudi Arabia.
Trump arrived in Saudi Arabia at the end of last week, and signed a deal worth $110 billion with the Arab kingdom.
In an official statement, Trump said the deal would "tens of thousands of new jobs in the US defense industry."
"Saudi Arabia is an extremist Muslim country, much more extreme than Iran was prior to the Iranian Revolution," Feiglin said. "Now, a country with a long history of wars against Israel and the West (most of the September 11 terrorists hailed from Saudi Arabia) will receive $350 billion dollars."
"Netanyahu is drunk from the current cooperation with the Saudis, and he will pay a hefty price for this pitiful 'cooperation.' We will lose sovereignty over the Temple Mount, we will lose the opportunity to move the US Embassy from Tel Aviv to Jerusalem, we will lose other opportunities.
"We will also grant legitimacy to extreme Islam's storehouse of US weapons, even though these weapons may be used against us in the future. It's exactly what happened before the Iranian Revolution.
"This is the time to tell the US President, 'thanks, but no thanks.' It would be better if the US did not provide aid for anyone in the Middle East, than for them to provide aid to our enemies. We'll be fine either way."
