U.S. President Donald Trump on Thursday intensified his accusations that NATO allies were not spending enough on defense and warned of more attacks like this week's Manchester bombing unless the alliance did more to stop militants.
In unexpectedly abrupt remarks as NATO leaders stood alongside him, Trump said certain member countries owed "massive amounts of money" to the United States and NATO -- even though allied contributions are voluntary, with multiple budgets.
His scripted comments contrasted with NATO 's choreographed efforts to play up the West's unity by inviting Trump to unveil a memorial to the Sept. 11, 2001, attacks on the United States at the new NATO headquarters building in Brussels.
"Terrorism must be stopped in its tracks, or the horror you saw in Manchester and so many other places will continue forever," Trump said, referring to Monday's suicide bombing in the English city that killed 22 people, including children.
"These grave security concerns are the same reason that I have been very, very direct ... in saying that NATO members must finally contribute their fair share," Trump said.
NATO Secretary-General Jens Stoltenberg defended Trump, saying that although he was "blunt" he had "a very plain and clear message on the expectations" of allies.
But one senior diplomat said Trump, who left the leaders' dinner before it ended to fly to Italy for Friday's Group of Seven summit, said the remarks did not go down well at all.
"This was not the right place or time," the diplomat said of the very public harangue. "We are left with nothing else but trying to put a brave face on it."
In another unexpected twist, Trump called on NATO , an organization founded on collective defense against the Soviet threat, to include limiting immigration in its tasks.
