Are we at war with Canada now?

Presidents have a history of leaving messes for following presidents to clean up if they're not of the same political party, but this takes the cake:

In his final days in power, President George W. Bush asserted U.S. military "sea power" over the oil-rich Arctic Monday, in another forceful rebuttal of Canada's claims of sovereignty over the Northwest Passage. . . . The Bush directive reiterates that the Northwest Passage is an international waterway -- a rebuttal of Canada's claim of sovereignty over what is emerging as a major global shipping route because of the shrinking polar ice cap -- and it highlights the boundary dispute in the resource-rich Beaufort Sea.

So in his last two weeks before leaving office, Bush claims Canada's territory as its own.

For the love of god, is he going to leave us at war?
