(CNN) -- The terrorist attacks on America on September 11, 2001, gave his administration a clear goal and him the resolve to find out who was responsible and "kick their ass," former President George W. Bush writes in his new book. In "Decision Points," Bush describes his reaction when his then-National Security Adviser Condoleezza Rice informed him of the crash of a third airplane into the Pentagon. "I sat back in my seat and absorbed her words. My thoughts clarified: The first plane could have been an accident. The second was definitely an attack. The third was a declaration of war," the former president writes in his 481-page book, which goes on sale Tuesday.
