The US has traditionally been neutral on the issue

Donald Trump said Saturday he would “love to see” a united Ireland, wading into a politically sensitive subject as he embarked on a two-day Irish visit that blurs the lines between his presidency and personal business interests.

After meeting Ireland’s Prime Minister Micheal Martin in Dublin, Trump said reunification of the Republic of Ireland and Northern Ireland – split for over a century – would be “a fantastic thing”.

“The way I look at it, it’s going to happen eventually. It may as well happen now,” he told reporters, adding though that “the UK will have something to say about it, obviously”.

The island of Ireland has been split between the Irish republic in the south and Northern Ireland, which is part of the United Kingdom, since 1921.
