Mrs Rooney branded the trial "horrible" in an interview with British Vogue last year.

In recent months, Trump has repeatedly called Canada the "51st state" of the US – and the White House has expressed a willingness to open up new areas of dispute all along the US-Canada border.In September, the president voiced designs on Canadian water in British Columbia in the west of the country, for instance, suggesting it could be piped to drought-parched California: "You have millions of gallons of water pouring down from the north… they have essentially a very large faucet".

Approximately 1,500 miles further east, the Great Lakes could become another site of potential conflict, as US officials told their Canadian counterparts they are considering withdrawing from treaties over their coordinated environmental regulation.And even further east, a library has become the unlikely setting for a flashpoint: built deliberately to straddle the Vermont-Quebec border as a symbol of cooperation between Canada and the US, the Haskell Free Library and Opera House used to be open to residents from both nations.However in March, America changed the rules so that Canadians are required to pass through immigration control before they access the building, with the US Department of Homeland Security claiming it was in response to drug trafficking.

Natural resources are another source of dispute. Canada has vast supplies of rare earth metals, gold, oil, coal and lumber – the kind of natural wealth that Trump has long prized.While Trump has disavowed any desire for Canada's lumber, energy stockpiles or manufactured products, in February Trudeau reportedly told a closed-door meeting of Canadian business and labour leaders that he saw it differently.

"I suggest that not only does the Trump administration know how many critical minerals we have but that may even be why they keep talking about absorbing us and making us the 51st state. They're very aware of our resources, of what we have, and they very much want to be able to benefit from those," the CBC quoted Trudeau as saying.

Jordan Heath-Rawlings, a Canadian journalist and host of The Big Story podcast, believes Trump wants Canadian resources, and that the president's annexation comments should be taken seriously.The same applies for the aid freeze that is causing such chaos in countries and organisations that have long depended on US funding - China may wish to fill the gap, despite an economic downturn.

On his first day back in office,, which is by far the world's biggest aid donor. Hundreds of foreign aid programmes delivered by USAID ground to a halt. Some have since restarted, but aid contractors describe ongoing chaos as the future of the agency hangs in the balance.

Trump's "America First" doctrine could further weaken Washington's position as a global leader, says John Delury, a historian of modern China and Professor at Yonsei University in Seoul."The combination of tariffs on major trade partners and freezing of foreign assistance sends a message to the Global South and OECD alike that the US is not interested in international partnership, collaboration," he tells the BBC.
