Unsuccessful Success: President Trump Meeting EU Leaders in Europe's Capital

"President Trump's failure to stand firmly behind that pledge is certain to worry our allies and embolden Vladimir Putin and others who want to see the alliance falter".

But he complained that "23 of the 28 member nations are still not paying what they should be paying. for their defence".

"NATO members must finally contribute their fair share and meet their financial obligations", he said as his 27 counterparts looked on in silence.

"Many NATO countries have agreed to step up payments considerably, as they should".

During the meeting, Trump did not restate commitment to NATO Article 5 - a provision of membership that says an attack on one member state is an attack on all member states.

Trump, who during his presidential campaign once called climate change a "hoax," made the announcement on Twitter ahead of the other nations pledging their commitment to the deal at the G-7 Summit in Taormina, Italy.

In almost 70 years of existence, Article 5 has only been invoked once - September 11, 2001 - and was the catalyst for NATO's involvement in the war in Afghanistan that followed.

"Terrorism is a threat, bad threat to all of humanity", Trump said, standing in front of a massive American flag at Naval Air Station Sigonella.

Under the agreement, which was reached by almost 200 countries, the Obama administration pledged to cut US greenhouse gas emissions 26 percent to 28 percent below 2005 levels by 2025, though it is not legally binding. "Look at the millions of cars they sell in the U.S. and we'll put a stop to that", said Mr Trump, railing about the trade imbalance between the two countries.

The first and only time that NATO countries have ever formally invoked their treaty commitment to defend one another occurred after the attacks on NY and Washington.

Other odd moments from this trip include the "grip and grit your teeth" handshake with new French President Emmanuel Macron, the failed attempts at hand holding with the first lady and video of Trump shoving aside Dusko Markovic, the prime minister of Montenegro, as the North Atlantic Treaty Organisation leaders got ready for their class photo.

James Comey, the former FBI director leading the Russian probe until Trump abruptly fired him, is still expected to testify before Congress about the memos he kept on conversations with the president that involved the investigation.

Dusko Markovic, Montenegro's prime minister, felt the wrath of Trump personally as he was abruptly shoved aside by the President before a photo op.

Terrorism, however, gave the President an opportunity to castigate those investigating him in the United States over his Moscow links.

British investigators are now refusing to share information about the case with US law enforcement.

Trump announced a review of the "deeply troubling" leaks and warned that those responsible could face prosecution, the White House said.

In Brussels, Trump sat in a morning meeting with top European Union leaders, where one emerged to say there were deep differences between them about whether the West can work with Russian President Vladimir Putin.
