Donald Trump has refused to rule out dropping a nuclear weapon on Europe.
In a Town Hall interview with MSNBC's Chris Matthews on Wednesday evening, the frontrunner in the race to become the Republican president said he would be "the last one to use nuclear weapons".
But when pressed by Matthews if he would attack Europe or the Middle East with nukes if he felt it necessary, Trump said he was "not going to take it off the table".
Matthews: "You might in Europe?"
Trump: "No. I don’t think so."
Matthews: "Well just say it: 'I will never use a nuclear weapon in Europe.'"
Trump: "I am not taking cards of the table. I’m not going not use nukes. But I’m not taking any cards of the table."
Matthews, who was clearly astounded by Trump's comments, told the Republican: "The trouble is when you said that, the whole world, David Cameron in Britain heard it, the Japanese who we bombed in 1945 heard it, they are hearing a guy running for president of the United States maybe using nuclear weapons. Nobody wants to hear that about an American president."
Trump asked the MSNBC host in reply: "Then why are we making them?"
Democratic frontrunner Hillary Clinton told MSNBC's Rachel Maddow on Wednesday Trump was "in over his head" when it came to foreign policy with his "national security ad-libbing".
Clinton said she did not think Trump "even studies or cares to understand" foreign policy.
Last night Trump u-turned on his call during the MSNBC interview with Matthews for women to suffer "some form of punishment” for having an abortion
"Are you going to, say, put them to jail?” Trump said to the host, adding: “There has to be some form of punishment.” When asked to clarify if he meant a punishment for women, Trump said, “Yeah,” though he hasn’t “determined what the punishment should be.
In a separate interview with CNN on Tuesday evening, Trump was told to stop behaving like a "five-year-old" child.
