President Trump exported the confrontational, nationalist rhetoric of his campaign across the Atlantic on Thursday, with an attempt to shame European leaders for not footing more of the bill for their own defenses and lecturing them to stop taking advantage of United States taxpayers. "First and foremost on counter-terrorism and I am sure I don't have to explain why, but some issues remain open, like climate and trade", Tusk, who represents the 28 leaders of the European Union, said.
President Trump is in Italy Friday for meetings with leaders of the biggest economies in the world.
During his presidential election campaign, Mr Trump welcomed the British decision to leave the EU.
Tied to this concern are the links between the Trump administration and Russian Federation, the country seen as the greatest threat to European stability by NATO allies on this side of the Atlantic. Milan Knezevic, leader of Montenegro's opposition and anti-NATO Democratic People's Party, said by phone that Trump's behavior "is clear proof that there's no such thing as equality in NATO", showing that the country is just a "smudge" on the alliance's map.
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.More news: 'I'm doing OK': Hillary Clinton delivers graduation speech at alma mater

Trump refused to say he would adhere to the mutual defense pact, known as Article V, though the White House later claimed that his very presence alongside twisted World Trade Center steel - a memorial outside North Atlantic Treaty Organisation headquarters - was evidence enough of his commitment. But the question of relevance still lingers. I don't take it any other way.
Where President Obama tried to encourage Iran to reform through the Iran nuclear agreement, President Trump sees a new alliance of Sunni Arab states and Israel, united against their common enemy Iran, as the key to curtailing terrorism and to a peace deal between Israel and the Palestinians.
"23 of the 28 member nations are still not paying what they should be paying and what they are supposed to be paying for their defence".
The day will feature a welcoming ceremony and concert at the remains of an ancient Greek temple, as well as a relentless number of meetings, many of which White House aides are hoping to keep short in order to keep Trump's attention. Article 5 has been invoked only once in NATO's history, after 9/11.
"Smaller countries can all show that they are doing a lot in terms of contribution". The hectoring tone was inappropriate to the occasion, and Trump ignored the increases many countries have made in their defense budgets. Trump is well known for his efforts to dominate male interlocutors with a firm handshake, often accompanied by an arm wrench: notable victims include the Japanese prime minister Shinzo Abe, who survived a 19-second power grip in February.
