Nuclear Issues

North Korea is warning of a pre-emptive strike after Sec. of State Rex Tillerson said that the U.S. could pursue military action over North Korea’s growing nuclear program.

The attacks in Brussels last month were a stark reminder of the terrorists’ resolve, and of our continued vulnerabilities, including in an area of paramount concern: nuclear security.

The attackers struck an airport and the subway, but some Belgian investigators believe they seemed to have fallen back on those targets because they felt the authorities closing in on them, and that their original plan may have been to strike a nuclear plant. A few months ago, during a raid in the apartment of a suspect linked to the November attacks in Paris, investigators found surveillance footage of a senior Belgian nuclear official. Belgian police are said to have connected two of the Brussels terrorists to that footage.

Simon Saradzhyan testified before the U.S. House of Representatives' Europe, Eurasia, and Emerging Threats Subcommittee Hearing on "The Threat of Islamist Extremism in Russia," on September 30, 2015. 

In his testimony, Saradzhyan asked: "Can the United States and Russia cooperate against the threat posed by the Islamic State of Iraq and Syria and other international terrorist organizations, even though the bilateral relationship has deteriorated in the wake of the crisis in Ukraine? My answer is they can and they will if they act in their best interest."

Iran and six world powers clinched a deal on Sunday curbing the Iranian nuclear program in exchange for initial sanctions relief. Sounds pretty good, but of course nothing is that simple and already Israel has called it a "historic mistake." Which is it? And what's going to happen next? Harvard Kennedy School professor and GlobalPost senior foreign affairs columnist, Nicholas Burns, weighs in.

Professor Burns discusses the shift in policy and tone coming from Iran, courtesy of its new president, Hassan Rouhani, and what that means for future relations between the U.S. and Iran.
