Speaking at CPAC, former UN ambassador John Bolton declared that our “biggest national-security problem is Barack Obama.” Why? In part because he “has done nothing to avenge Chris Stevens’s death.” Stevens was killed in the 9/11/12 Benghazi attack. “That is a terrible lesson for our adversaries,” Bolton said. “Under Barack Obama you can murder his personal representative and get away scot-free.” Unfortunately, the price we pay for electing Obama is steep. “Ignoring our national security is the Obama doctrine,” he concluded.
