I don't know, maybe it's just me, but when I heard Prs. Bush say, "Bring it on!" it brought back memories. Memories of being a Specialist in Saudi Arabia when Hussein threatened to bring "The Mother of all wars" to the U.S. led coalition. Now, I realize we were a bunch of young, and highly motivated paratroopers, but our response to the was, in fact, "Bring it On!!!!" The words almost became a mantra every time we heard "Mother of all wars".
Anyway, I'd much rather hear a president use words like, "Bring it On!" than "An act of terrorism totally outside the bounds of international law and diplomatic tradition. a crisis [that] calls for firmness and restraint." Yeah, Prs. Carter, that one worked.
