"We showed our united commitment and our determination to continue and to strengthen our fight against terrorism", Gentiloni said after the leaders signed a document that also expressed solidarity with Britain after the suicide bomb attack in Manchester on Monday (22 May) that killed 22.

"He knows that in the USA there's very strong opinions on both sides, but he also knows that Paris has important meaning to numerous European leaders, and he wants to clearly hear what the European leaders have to say", Cohn added.
The leaders agreed to a joint statement on combating global terrorism, Cohn said. Kohn told reporters Wednesday evening that Trump "knows that Paris has important meaning to numerous European leaders". And Trump is likely to face more pressure to stay in the climate agreement, bolstering the arguments Trump's Secretary of State Rex Tillerson, daughter Ivanka Trump and son-in-law Jared Kushner - both senior advisers - have leveled to urge him to stay in the deal.

The gap between Trump and other G-7 leaders on climate underscored his isolation from Europe on some major issues.
If Trump does decide to pull out of the deal, it would be quite easy: The administration could remove the country from the 1992 United Nations Framework Convention on Climate Change that set up the Paris agreement.
"He listened very acutely to the other leaders in the room", Cohn said. On the one hand, Trump's resistance may force the G7 to downgrade its climate ambitions and show how USA denial is already taking its toll on the global stage.
"The United States is considering its position in relation to these matters and what its policy is going to be, but there was no doubt around the table about how important this issue on climate change is", May said.
