September 11, 2001 is a day that changed the course of America forever. On that fateful Tuesday morning, nearly 3,000 of our citizens lost their lives in a senseless act of terrorism. I was in Berlin that day as the newly installed U.S. Ambassador to the Federal Republic of Germany.  It was my second day on the job.  The first day was spent touring the Embassy, meeting my new staff and receiving my first security briefing.
