Meeting with other heads of state of NATO countries in Brussels, the president continued with themes he has raised many times in the past - that other countries don't meet their dues or defense spending commitments to the trans-Atlantic defense alliance and that Germany keeps afloat Russian Federation, the organization's top adversary, by purchasing energy from it. NATO, the 70-year-old intergovernmental military alliance that's devoted to collective worldwide security, has come under attack from Trump.
North Atlantic Treaty Organisation members are required to spend 2 percent of their GDP on defense and are supposed to pay dues, and many countries are behind on both.
Trump said he made his anger clear to allies on Wednesday.
"There is a communiqué that was published yesterday. It's very detailed", Macron said, according to the AP.
While Germany has not yet met that goal, it has until 2024 to do so.
Trump lashed the German government on the project during a breakfast meeting with NATO Secretary General Jens Stoltenberg in Brussels on Wednesday.
Around eight members of the 29-country alliance are expected to reach the 2% target this year. Most officials and the invited leaders of non-NATO Afghanistan and Georgia were ushered out.
TRUMP, at the subsequent news conference with May: "I don't know what they're going to do, but whatever you do is OK with me".
"I don't understand why Germany would be so in favor of supporting that particular supply source instead of diversifying", said Corker, the chairman of the Senate Foreign Relations Committee.
Trump said he wanted "peace all over the world, that's my goal", and he wanted to achieve this by building up the military, with his dream to have the best military equipment in the world and never have to use it.
"I just don't know him very well".
Earlier Thursday, Trump called out US allies on Twitter, saying, "Presidents have been trying unsuccessfully for years to get Germany and other rich NATO Nations to pay more toward their protection from Russian Federation".
"Everybody in the room thanked me", he said.
"President Trump created for the second day a crisis on [NATO] spending".
The president also described Putin as his "competitor".
The attack against a core ally comes days before Trump is set to meet one-on-one with Russia's Vladimir Putin.
As for what he and Putin will discuss, Trump said Syria will be a main topic, as will Russia's attempts to interfere in the 2016 election that put Trump in the White House.
Moscow is eager to go ahead with the Nord Stream 2 pipeline for it can double the gas exports to Germany under the Baltic Sea while Washington is upset with the idea, even saying that firms that invested in the pipeline risked sanctions, the report added. "I made clear that we are on this path. I'm sorry you're spending so little'".
Woody Johnson, the USA ambassador to the United Kingdom, dismissed the significance of the protests, telling Fox News that one of the reasons the two countries are so close "is because we have the freedoms that we've all fought for". People are paying money that they never paid before.
