More than 50 progressive advocacy groups on Monday sent a letter to former Vice President Joe Biden, the presumptive Democratic presidential nominee, urging him to make concession to the left on Middle East policy.

The groups, led by Demand Progress, are calling on Biden to return to the Iran nuclear deal, leverage military aid to Israel to secure concessions over its occupation of the West Bank and blockade on the Gaza Strip and repeal the 2001 military authorization that serves as the legal basis for most US counterterrorism operations throughout the world.

“A failed post-9/11 agenda has resulted in global instability, countless lives lost and widespread violations of human rights,” said Yasmine Taeb, the senior policy council at Demand Progress. “By committing to prioritize serious diplomatic engagement and respecting congressional war powers, our leaders can end the forever wars and deliver an agenda more aligned with our values.”  

Why it matters: Biden has already committed to reentering the Iran deal and negotiating a follow-up agreement. However, he has not yet publicly disclosed his position on repealing the 2001 military authorization. (House Democrats attempted to repeal the 2001 authorization within eight months as part of a defense spending bill last year, but had to abandon the effort as part of a compromise with the Republican-held Senate.)
