In fact, those of us on the daily thread USA vs. Clinton (now "America the Right Way") used it as our rallying cry during the Florida recount.
The one thing I most love about President Bush is that he has a sense of history, and his speechwriters echo both history and literature. Not in the daily, bread and butter speeches, of course, but in the really important speeches.
I think that when we are told about Iraq, we are going to hear a St. Crispin's speech.
