On the list of Middle East policy mistakes this century, this is the second biggest. Let's hope it doesn't prove the first.

WASHINGTON—Third Way released the following statement from Mieke Eoyang, Vice President for National Security:

"Today President Trump breaks America's promise to allies and adversaries alike by walking away from a nuclear agreement that was blocking Iran from getting a nuclear weapon. This agreement stopped and rolled back Iran's nuclear program—the most serious security threat the US and our allies faced in the region. Now, Iran could race for the bomb and our allies may not willing to give negotiations a second try, having lost this opportunity. This contrarian decision flies in the face of the best advice of our military, our allies, and America's national security.

"The deal was designed to address the most important security threat, not every security threat that Iran poses. But this agreement was the foundation upon which the U.S. and our allies could build to curb Iran's support for terrorists, its threats to its regional neighbors, and its human rights abuses.

"President Trump’s decision to walk away alone sends a message to our adversaries that they cannot take the US at its word in negotiations over denuclearization in Iran, the Korean Peninsula, or anywhere else. The President's decision to reimpose sanctions means that the US has lost the international leverage necessary to bring Iran back to the table. Unfortunately, the President doesn't bear the consequences of breaking the deal alone. We all now bear the risk of a nuclear-armed Iran or yet another deadly and avoidable war in the Middle East at a time when we can least afford it.

On the list of Middle East policy mistakes this century, this is the second biggest. Let's hope it doesn't prove the first."
