Somebody wrote: "The undebated issue is why we are buying anything at all - we can't afford a fleet of sufficient size to actually defend the nation against the only two powers who could conceivably invade."

The only two nations who could conceivable invade?

Are you kidding me?

In case you don't follow the news, the might nation of, um, Denmark invaded Canada's Hans island a few years ago, erected the Danish Flag, and their top legal representative declared: "We consider Hans Island to be part of Danish territory".

Sorry, but it is foolish to assume that the only possible threats to Canadian territory can come from what, the USA and Russia, I assume was the suggestion? To the contrary, the goodies in and around the Northwest Passage, from oil to fish to land to minerals, are of interest to other countries, especially in times of war...
