Edit: Tosk, just saw your post.  I happen to disagree.

Strategy also encompasses one's major objectives, does it not?  The famous "Anaconda Plan" in the Civil War was a strategy, not a tactic.  One's strategy should be designed in such a way to capitalize on tactics where you can dominate the adversary.  In the Union's case, the Anaconda Plan was dependant on the Union being able to field large armies on both sides of the Appalachian Mts, and to be able to win battles through numerical superiority.  Had they not had numerical superiority, the Anaconda Plan would not have worked well.  Thus, the strategy is molded by one's tactics.
