How Drumpf is going to annex Canada and Greenland if canadians and danes reject peaceful incorporation? Greenland is an easy target since it's just a giant snow island with 50k inhabitants and US military bases(locals should be quickly pacified if they decide to chimp out). Canada, on the other hand, is a relatively large country but most canadians live along US border. Military actions should be taken only if canadians refuse annexation after total ban on trade with US(economically speaking, Canada is very dependent on its giant neighbor).
