LONDON (Reuters) -U.S. President Donald Trump said he believed Britain would fight to defend the United States but suggested he could not say the same for the European Union, a factor in his decision not to sign a trade deal with the bloc.
Trump told the BBC in an interview published on Tuesday that he also still had doubts about support from NATO members, even after they agreed to increase defence spending.
"One of the problems with NATO, as I said, we have to fight for them, but will they actually fight for us if we had a war?"
"And I'm not sure I can say it, but I will say this, I believe that the UK would fight with us," he said.
"I think that they would be with us. I'm not sure that a lot of the other countries would be."
Trump said this was a factor in his willingness to grant Britain some exemptions from his tariff programme. In contrast, he has threatened a 30% tariff on European goods.
"Look, that's why I made a deal with them, and I haven't made a deal, I mean, I've made some other deals, but for the most part, in terms of your competitors, and in terms of the European Union, I haven't made a deal," he told the BBC.
The only time NATO has activated Article 5 - the cornerstone of its founding treaty which stipulates that an attack on one is an attack on all - was on behalf of the United States, in response to the Sept. 11, 2001 attacks.

Trump expressed confidence that the UK would fight to defend the United States, contrasting this with his doubts about the European Union's commitment.
Trump voiced concerns about whether NATO members would support the US in a conflict, despite their agreement to increase defense spending.
Trump indicated that his willingness to grant the UK exemptions from tariffs was influenced by his belief in their support, while threatening a 30% tariff on European goods.
British troops supported the US in conflicts in Afghanistan and Iraq, although the size of the UK army has since reduced.
NATO's Article 5 states that an attack on one member is considered an attack on all, and it has only been activated once, in defense of the United States.
