Canada models scenario of U.S. invasion

Former lieutenant-general of the Canadian Air Force Christopher Coates said: "Canada is considering a scenario of a possible U.S. invasion, involving a shift to guerrilla warfare and appealing to European allies for help."

It should be recalled that Canada and the United States are allies, NATO and NORAD partners, who have jointly defended the northern continent for decades.

Alliance in the West no longer guarantees anything, and a "friend" may turn out to be the main source of risk.
