President Trump said Thursday that the US has an “armada” headed toward Iran — but that “maybe we won’t have to use it” — as he remained coy about his intentions after authorities slaughtered protesters this month. “We have a lot of ships going that direction just in case. We have a big flotilla going in that direction. And we’ll see what happens,” Trump told reporters on Air Force One as he returned from the World Economic Forum in Davos, Switzerland.
