Trump will meet with Putin next week, and met with Kim at the incredibly weird summit in Singapore in June. While he inaugurated the vast glass structure, North Atlantic Treaty Organisation officials and diplomats flinched as Mr Trump joked: "I never asked, once, what the new North Atlantic Treaty Organisation headquarters cost - I refuse to do that".
She said she expected unanimous agreement among NATO's 29 members on proposals to reform the alliance command structure, increase readiness for possible threats from Russian Federation on NATO's eastern flank, add a new training mission for Iraq and increase counterterrorism efforts in Afghanistan.
Member countries are anxious that Trump will spurn them and threaten to unravel the organization, their fears stemming from the G7 meeting last month.
He accuses European NATO allies of freeloading, telling a rally this week that they had treated the USA like "schmucks".
Trump also took aim at what he indicated were trade inequities with the EU on Monday in an indication he will attempt to link the US commitment to European security with trade.
Sources told CNN that while Trump has already met the Russian president, the private meeting will allow Trump to develop the relationship between the two leaders. Most of the non-US Nato members are moving closer to the entirely reasonable goals of spending 2% of gross domestic product on defence and 20% of that on modern equipment.
And despite Trump's outward rhetoric, the USA contribution hasn't gone down, suggesting that nervousness around the summit may be overplayed, said Michaels.
"I'm going to tell NATO: You've got to start paying your bills".
However, Putin may also seek an outcome in which Trump can declare victory in the hopes that Russian Federation may eventually get what it wants - legitimizing its annexation of Crimea, easing of US sanctions, and concessions on arms control.
Trump had also invited Putin to the White House, which would be the first such visit since 2005, Kremlin aide Yury Ushakov said to Russian journalists in April.
"It will become increasingly hard to justify to American citizens why some countries continue to fail to meet our shared collective security commitments", Trump said in a letter addressed to Norwegian Prime Minister Erna Solberg seen by Bloomberg News.
