Donald Trump defended his tight-lipped anti-terror strategy on Monday, claiming the American public, along with enemies of the U.S., do not need to know the details of his planned military campaign against the Islamic State.

“I just want to say that we are going to hit ISIS, but I want to say this: the American public doesn’t need to know the date, time [and] second that we’re going to attack, that we’re going to attack from the eastern quadrant,” Trump told a group of veterans at a town hall in Herndon, Va., hosted by the Retired American Warriors PAC.
