"Also by floating proposals that the Danish *state* and British *monarch* cede their stewardship of Greenland and Canada to the USA."
Yes, one still can be tedius and argue that the Throne's veto over Canadian legislation doesn't qualify as 'stewardship' (since it is supposed to be symbolic)
The point of my comment (which I maintain) is that Britain has strong ties with Canada, and so Trump butting in, pushing for Canada to abandon the Commonwealth to become a state, comes across as hostile.
Canadians may find the threat more alarming than Britons, but it's welcomed by neither people.
