No, that's a managed disagreement. It's been a long-standing disagreement. Canada and the U.S. tend not to punish each other for concerns in one area through another. For example, when the U.S. and Canada have disputes about softwood lumber, it doesn't mean that in NORAD the U.S. refuses to speak to us.
The U.S. is usually very satisfied with the level of commitment we have. There may be small jabs and disagreements, but overall, the defence of North America is the number one priority of both states, and nothing yet has changed that fact.
