Telegraphing the plan

This is my question: doesn't a speech like Bush's, in which a strategic plan is outlined, give the enemy the advantage of knowing in advance what the approach will be, and take away any element of surprise? True, the details aren't known; but the broad outline is.

Democracies demand such things, especially modern democracies. But it seems to be a potential problem of some magnitude in waging any war, conventional or assymetrical, does it not?
