Before the start of business, Just Security provides a curated summary of up-to-the-minute developments at home and abroad. Here’s today’s news.


A group of 47 Republican senators wrote an open letter to Iran’s leaders, warning them that any agreement concluded with the Obama administration could be revoked by the next president “with the stroke of a pen” and “future Congresses could modify the terms of the agreement at any time.” The letter, authored by freshman Senator Tom Cotton, was signed by Majority Leader Mitch McConnell and a number of potential 2016 presidential candidates.

The GOP letter deepens the battle with the White House over the Iran negotiations. President Obama said “it’s somewhat ironic to see some members of Congress wanting to make common cause with the hardliners in Iran,” in response to the letter. [Washington Post’s Greg Jaffe and Sean Sullivan]  Vice President Joe Biden sharply criticized the Senate Republicans in a lengthy statement, stating that their letter “sends a highly misleading signal to friend and foe alike that that our Commander-in-Chief cannot deliver on America’s commitments—a message that is as false as it is dangerous.” [Huffington Post’s Igor Bobic]

The Iranian foreign minister dismissed the letter as a “propaganda ploy.” In his statement, Javad Zarif said:

“I wish to enlighten the authors that if the next administration revokes any agreement with the stroke of a pen, as they boast, it will have simply committed a blatant violation of international law.”

Democrats criticized the letter for interfering with international negotiations, with Senate Democratic Leader Harry Reid accusing the signatories of “empowering the ayatollahs.” [The Hill’s David McCabe]

Seven Republican senators refrained from signing the letter amid concerns that it could undermine the GOP strategy on a nuclear deal. Senate Foreign Relations Committee chair Bob Corker said the letter could detract from his ultimate goal of obtaining a veto-proof majority for a bill that would require congressional approval for an Iran deal.

Republicans are “crossing a dangerous new line” by seeking to undermine U.S. foreign policy, explains Max Fisher at Vox.  The GOP letter “undoubtedly” offers Iranian hardliners “another argument to use in opposing an agreement,” argues Carol Giacomo at the New York Times.  And the Wall Street Journal’s Gerald F. Seib explores whether Congress could “blow up” international talks conducted by a U.S. president and involving all major global powers.
