THE HAGUE, Netherlands — NATO Secretary-General Mark Rutte praised President Donald Trump for making Europe ''pay in a BIG way,'' as leaders gathered in the Netherlands on Tuesday for a historic summit that could unite them around a new defense spending pledge or widen divisions among the 32 member countries of the security alliance.
The U.S. president, while en route, published a screenshot of a private message from Rutte saying: ''Donald, you have driven us to a really, really important moment for America and Europe and the world. You will achieve something NO American president in decades could get done.''
''Europe is going to pay in a BIG way, as they should, and it will be your win,'' Rutte wrote. NATO confirmed that he sent the message.
Rutte appeared unconcerned that Trump aired it, telling reporters: ''I have absolutely no trouble or problem with that because there's nothing in it which had to stay secret."
Trump arrived early in the evening after injecting uncertainty over whether the U.S. would abide by the mutual defense guarantees outlined in the NATO treaty. ''Depends on your definition,'' he said. Rutte said he has no doubt about the Article 5 guarantee, which says an armed attack on one member is an attack on all.
On Wednesday, the allies are likely to endorse a goal of spending 5% of their gross domestic product on their security, to be able to fulfil the alliance's plans for defending against outside attack. Trump has said the U.S. should not have to.
Spain has said it cannot, and that the target is ''unreasonable.'' Slovakia said it reserves the right to decide how to reach the target by NATO's new 2035 deadline.
''There's a problem with Spain. Spain is not agreeing, which is very unfair to the rest of them, frankly,'' Trump told reporters.
