When our embassy is attacked in Benghazi by terrorists and there is no response, you get more bad behavior. When Russia invades Ukraine and there is no response, you get more bad behavior. When Syria crosses the red line and there is no response, you get more bad behavior. When Iran launches tests of ballistic missiles and there is no response, you get more bad behavior. When North Korea attacks Sony Pictures and there is no response, you get more bad behavior. In other words, Mrs. Clinton, you cannot lead from behind. We must respond when we are attacked or provoked.
