But he also acknowledged that Trump is right on spending, saying "dear Europe, spend more on your defence, because everyone respects an ally that is well-prepared and equipped".
Member countries are anxious that Trump will spurn them and threaten to unravel the organization, their fears stemming from the G7 meeting last month.
President Donald Trump is the wild card heading into this week's North Atlantic Treaty Organisation summit, as allies worry about his priorities for the meeting, leadership style and upcoming sit-down with Vladimir Putin on the heels of a rocky G7 summit with some of the same countries last month. He also has placed Germany at the centre of his complaints about a U.S.
On his own trip to the United States earlier this year, Johnson said that Trump could be eligible for a Nobel peace prize if he pulls off a nuclear disarmament deal with North Korea. And it could help promote acceptance of Trump's accurate assertion that the United States and the West must deal with reemergent Russia-despite the prevailing narrative that Trump is Putin's lapdog, which the mainstream media use to try driving Trump from office.

One can not rule out the possibility that Trump lacks the mental capacity to understand the basic form of America's most important alliance.
During his first meeting at the group's headquarters in Brussels past year, Trump suggested that members who haven't been paying their fair share should be required to pay back dues. The NATO chief said that the Europeans and Canada are projected to spend around US$266 billion more on defence by 2024.
Derek Chollet, executive vice president of the German Marshall Fund of the United States, a think tank, says there is a clear connection between Trump's criticism of German defense spending and reports that the Pentagon has undertaken a review of the cost of keeping troops in Europe. "NATO has not treated us fairly, but I think we'll work something out".
A country's defense contribution shouldn't be measured only as a percentage of GDP, but also in terms of troops and hardware, she said in an interview with Bloomberg Television in Berlin.
