With a European Union strained by powerful forces of the left and right struggling for supremacy from Britain to the Baltics, with immigrants clamoring for entry and ever newer torments from its ancestral enemy Russia, NATO has been a single constant that has stood largely unchallenged. It's ironic that it's the American president himself who seems intent on undermining the alliance, whose vow of mutual cooperation was last triggered after the 9/11 terrorist attacks on NY and Washington.
EU President Donald Tusk stepped up to the fight with his own salvo against Trump on Tuesday, telling him to "appreciate your allies" and reminding him Washington that Europe had come to its aid following the 9/11 attacks.
Mr Trump insisted that "the United States commitment to North Atlantic Treaty Organisation remains very strong, but primarily because of the spirit that everyone has, the amount of money they're willing to spend... the level of spirit in that room is incredible". "It's very detailed", Macron said, according to the AP.
He was referencing the U.S. television show that aired from 1957-1966 about a criminal defense attorney named Perry Mason who would often prove his clients' innocence by implicating another person.
It was a classic Trump performance - bluster, confrontation and demands followed by a unilateral declaration of victory - but his claim was quickly dismissed by the leaders of Italy and France, who disputed they had made any new pledges for increasing spending.
Al Jazeera's diplomatic editor, James Bays, reporting from the Belgian capital, however, said that based on interviews with sources, "nothing it seems, in the closed-door meeting, was resolved".
He insisted it had been a "very good" summit because of the frank and open discussion it had hosted.
"I'm not going in with high expectations but we may come out with very surprising things", Trump said.
According to the US Energy Information Administration, US exports of LNG soared from 0.5 billion cubic feet per day in 2016 to 1.94 billion cubic feet per day previous year.
US President Donald Trump launched a strong verbal attack on Germany on Wednesday (11 July) for its support to the Nord Stream 2 gas pipeline, aimed at bringing more Russian gas to Germany under the Baltic Sea.
The head of the Polish president's National Security Bureau, Paweł Soloch, said that US President Donald Trump's opinion "is important if the project is to be blocked". 4 per cent is what people should be spending.
Canada was never expected to agree to Trump's spending demands.
Perry said that new LNG expert terminals are coming on line in the eastern United States and that USA and European scientists and engineers are working together to improve supply.
"Yesterday I let them know that I was extremely unhappy with what was happening and they have substantially upped their commitment", President Trump told reporters, going on to repeat the claim that he had secured new commitments 10 more times during a press conference in Brussels.
"(The) 2 per cent (figure) was a range, a goal, now it's a commitment, it was like this amorphous number out there and now it's a real commitment", he said.
Trump has said next week's meeting with Putin "may be the easiest" part of his European tour. "I hope you have no doubt this is an investment in our security, which can not be said with confidence about Russian & Chinese spending".
