Trump to be "really tough" on NATO allies: Tillerson

BRUSSELS (Reuters) - U.S. President Donald Trump will be "really tough" when he meets his NATO allies for the first time in Brussels on Thursday, demanding that they raise their defense spending, U.S. Secretary of State Rex Tillerson said. Tillerson told journalists onboard the Air Force One that Trump "really wants NATO members to really step up and meet their obligations under burden-sharing." "I think you can expect the president to be really tough on them," Tillerson said. "That's going to be the core of his message to NATO." Tillerson added that Trump thought it important for NATO to join an international coalition fighting the Islamic State and that the U.S. president supported the Western military alliance's mutual security guarantees.
