Before leaving on Thursday for a visit to the United Kingdom, Trump called US commitment to the alliance "very strong", and referred to the two-day summit as "fantastic" characterized by "a great collegial spirit".
As a result, he continued, "NATO is much stronger than it was two days ago".
"Yesterday I let them know that I was extremely unhappy with what was happening", Trump said at an impromptu press conference, adding, "Now we are very happy". Everyone has agreed to substantially up their commitment.
He also said meeting the queen would be an experience Trump "will really cherish".
Going into the week he was pressuring them to spend 2 percent of their gross domestic product (GDP) on defense, a figure that was established in 2002 and reaffirmed in 2014 when the allies not meeting the target pledged to reach it within a decade.

"There was a commitment to reverse that declining investment and start moving toward two per cent and that's exactly what we agreed with as a government when we came in".
Hours later, he and German Chancellor Angela Merkel met privately and discussed the pipeline, each reaffirming the partnership between the USA and Germany.
He added that Trump makes a fair point in warning that Germany relies too heavily on Russian Federation for energy, recalling that Putin has used his control of gas supplies as a weapon against Ukraine.
Trump insisted that he would bring up key subjects including Syria, although he once again failed to rule out recognising Russia's annexation of Crimea.

Since exiting the Iranian nuclear deal, President Trump has demanded that our European allies join the U.S.in reimposing sanctions. Russian Federation is far from happy to see a US-led military alliance encroaching on its border.
"Everybody's talking about it all over the world, they're saying we're paying you billions of dollars to protect you but you're paying billions of dollars to Russian Federation". "Not acceptable! All NATO Nations must meet their 2% commitment, and that must ultimately go to 4%!"More news: Fiat workers 'to strike over Cristiano Ronaldo signing'
The Daily Mail runs with Mr Trump wading into the Brexit debate, saying the president delivered "some typically blunt home truths".
"I [also] want to delve into Vladimir Putin and what he wants for his country", said Wallace. "He may deny it", Trump told reporters. "They like me a lot in the U.K". "I made the point for Germany that we know we have to do more".
In particular, Trump did not meet with Romanian President Klaus Johannis.
Trump somewhat surprisingly demanded the 2% target be raised to 4%, although this was not reflected in the eventual summit declaration. "And the United States is being treated much more fairly".
"NATO Secretary-General Jens Stoltenberg is sidestepping questions about whether President Donald Trump has asked his allies to double their defence spending ambitions".
"We are increasing our defence budget". But also, that we are doing this already since many years. The leaders, including Trump, had signed on to a statement that highlighted agreement on a plan to improve the readiness and mobility of the armed forces across the Continent, and they agreed on tough language aimed at Moscow. That was just one of several helicopter rides on the agenda for Trump, whose staff opted to keep him largely out of central London and the swarms of demonstrators who are likely to provide some of the defining images of his first official trip to the United Kingdom.
