However, Mr Trump's intervention prompted an immediate response, with North Atlantic Treaty Organisation members going into an emergency session while the US President held a remarkable press conference where he said: "We are doing numbers like we've never seen before".
Hodges said Trump has a valid point - that allies should be spending more on defence - but his fixation on the two per cent target is blinding him to the fact that North Atlantic Treaty Organisation partners make other types of contributions.
The president will also be attending a pair of meetings of the North Atlantic Council before he departs for the United Kingdom. One notable but often forgotten example is that Trump's son, Donald Trump Jr., called the claims of Russian Federation hacking the DNC "phony" and "lies" on July 11, 2016.
"I thanked President Trump for his support in responding to the appalling use of a nerve agent in Salisbury, after which he expelled 60 Russian intelligence officers", May said after talks with the United States leader at the Chequers residence in Buckinghamshire on Friday.
That came despite Trump pushing North Atlantic Treaty Organisation leaders behind closed doors, unsuccessfully, to increase the North Atlantic Treaty Organisation defence spending target to four per cent of GDP.
"We're very happy and have a very, very powerful, very, very strong North Atlantic Treaty Organisation".
"It was important for the president to know what information we've uncovered because he's got to make very important decisions for the country", Rosenstein said.
As for Trump's demand, Freeland said Canada was a North Atlantic Treaty Organisation co-founder and has contributed to every single alliance mission.More news: Liverpool's Jurgen Klopp backs Dejan Lovren after Croatia World Cup run

Schumer says Trump should cancel his meeting with Putin until Russian Federation takes steps to prove it won't interfere in future elections.
"All NATO Nations must meet their 2% commitment, and that must ultimately go to 4%!"
NATO Secretary General Jens Stoltenberg called an emergency session of all 29 allies to address Trump's demands, and the U.S. leader said his hectoring had paid off.
"The President said his meeting with the Russian leader may be the easiest" part of his European tour, with massive protests expected over his presence in London.
But French president Emmanuel Macron denied any change in policy as a result of Mr Trump's involvement, saying the allies had simply reaffirmed their earlier commitment to increase defence spending to two per cent of gross domestic product by 2024.
Prime Minister Justin Trudeau said Canada hadn't committed to spending new money on defence at this week's meeting in Belgium, but pointed to his government's plan to increase the defence budget by 70 per cent over the next decade to $32.7 billion. "I don't know that is what they voted for".
"Secretary General Stoltenberg gives us total credit - meaning me, I guess, in this case". And Trump should definitely not meet him alone. "I'm pleased that the Justice Department is following the facts wherever they may lead, despite Donald Trump's risky distortions and his refusal to acknowledge the conclusions reached by the American intelligence community".
