At last night's Republican debate, Michele Bachmann—calling Pakistan "too nuclear to fail"—made the alarming claim that six attempts had been made on the nation's 15 nuclear sites. "This is more than an existential threat. We have to take this very seriously," she said. Some suspected that the candidate—who sits on the House Intelligence Committee—had accidentally leaked classified information, but her claim, though somewhat misleading, is based on reported incidents, CNN finds.
Six terrorist attacks—including a school bus bomb and a munitions factory blast—have occurred at or near nuclear sites in Pakistan, according to Jane's Terrorism and Insurgency Center, but they do not appear to have been attempts to seize the country's nuclear weapons. Earlier this month, a State Department spokesman said Pakistan "is well-aware of the range of potential threats to its nuclear arsenal and is accordingly giving very high priority to secure its nuclear weapons and materials effectively."
