Ambassador and Belfer Center Senior Fellow Wendy R. Sherman, the former U.S. Undersecretary of State for Political Affairs, will lead HKS’s Center for Public Leadership and become a professor of the practice of public leadership in January. Sherman, who negotiated with the North Koreans and the Iranians on nuclear issues, is the author of Not for the Faint of Heart: Lessons in Courage, Power, and Persistence.

The Trump administration is right that Iranian behavior destabilizes the region, but wrong when it says that such behavior contradicts the “spirit” of the agreement and that he is therefore justified in refusing to certify Iran’s compliance. In fact, Iran’s troubling foreign policy is precisely why the deal was necessary in the first place: An Iran armed with a nuclear weapon would be far more threatening to regional and global security.

The National Security Advisory Group sounds a warning, raising awareness about the state of our ground forces today and the very real risk that poses to our future security. The group also proposes an action plan for restoring the health and vitality of the U.S. military.

The gravest threat facing Americans today is a terrorist detonating a nuclear bomb in one of our cities. The National Security Advisory Group (NSAG) judges that the Bush administration is taking insufficient actions to counter this threat.
