The Canadian question is now resurrected. Yesterday Condi announced that she would not visit Canada due to their non-participation in funding the missile defense shield.
Canada is hoping that TW is right and that a missile defense shield will never really work. Or that if it does, the US will still shoot down missiles headed for Canada out of the goodness of its North American-loving heart, or with the notion that the US can't be sure exactly where missiles are headed. It is an interesting gambit made for solely political purposes - according to
the NYT story, the US was looking mostly for moral support on this and not money.
