" Canada is your best friend, largest trading partner, and closest ally, but we are also an independent country. Keeping some distance will be good for both of us. If we look as though we're the fifty - first state of the United States, there is nothing we can do for you internationally, just as the governor of a state can't do anything for you internationally. But if we look independent enough, we can do things for you that even the CIA cannot do."
