Former President Donald Trump is facing widespread criticism after saying he would encourage Russia to attack NATO allies who pay too little money into the military alliance. Trump made the comment during a campaign rally in South Carolina.

Donald Trump: “One of the presidents of a big country stood up, said, 'Well, sir, if we don't pay and we’re attacked by Russia, will you protect us?’ I said, 'You didn't pay? You’re delinquent?’ He said, 'Yes, let's say that happened.’ 'No, I would not protect you. In fact, I would encourage them to do whatever the hell they want. You got to pay. You got to pay your bills.' And the money came flowing in.”

NATO Secretary General Jens Stoltenberg issued a statement in response to Trump’s remarks: “Any suggestion that allies will not defend each other undermines all of our security, including that of the U.S., and puts American and European soldiers at increased risk.”
