office facing a real crisis. a man you can bait with a tweet is not a man we can trust with nuclear weapons. i can't put it -- i can't put it any better than jackie kennedy did after the cuban missile crisis. she said that what worried president kennedy during that very dangerous time was that a war might be started, not by big men with self control and restraint, but by little men, the ones moved by fear and pride. america's strength doesn't come from lashing out, it relies on smarts, judgment, cool resolve and the precise and strategic application of power, and that's the kind of commander in chief i pledge to be. and if we're serious about keeping our country safe, we also can't afford to have a president who's in the pocket of the gun lobby.
