Canada

The irony is, the only country that has EVER, in Canada's entire history as a nation, shown any intent or interest. either by word or deed, into attacking Canada is ... the United States of America.

No other country has even hinted, ever, that it wants to or will or is planning to attack Canada the Nation.

England and France had a tiff over who would control the land that would be called Canada, and both ended up having a partnership in the new Nation of Canada. After that, they showed no interest. Well, maybe a comment or two from Chuck DeGaul.

Not even in either of the two World Wars.

In fact, it was not until the mid 1940's that America proposed that Canada and the United States should be friends and partners in the military sense. Before that, we always had a healthy fear of the military intentions of America towards us.
