The number one danger, even when it comes to nuclear power, remains Isis. The summit on nuclear security in Washington (March 31-April 1) closes the cycle that Obama had opened with a keynote speech in Prague in 2009. At the time, the priority was to reduce atomic arsenals and prevent the proliferation of nuclear warheads. Today the alarm is that "the crazed terrorists of ISIS" can take possession of the material to manufacture deadly radioactive devices.
In the afternoon, Scott Roecker, director of the Department for Nuclear Threat Reduction, a member of the National Security Council, explained that "materials are stocked around the world that would make it possible to assemble 50 atomic bombs". Roecker was explicit: “We know the terrorists are trying to do them; we know there is information out there to do that.”
