You've just had a terrible argument with you lover, and it looks as though your many good times together suddenly mean nothing. The course you are on now is going straight to Splitsville. That person who was once your closest confidant and friend looks at you through big, wet tears and asks, "How could it have come to this?" Now's the time to look at the big picture: history (and, yes, herstory, too). What were the most defining moments in human culture that lead the world to where it is now-and led you to this tragic parting of ways?

Has everything changed? You're darn tootin' it has. Of all recorded human history, nothing has been as significant or unprecedented as the cowardly act of evil doers here on our home soil. (Note: this sentiment does not apply to our international readers.) Nothing will ever be the same again. Now, when we chant, "U! S! A! U! S! A!" we mean it in a totally new way, aware that our safety and our complacency can never be taken for granted again. Now, when we shop, we know that patriotism is behind our purchase of the new X-Box.
