Tyler is a former U.S. Secretary of Defense. The man who he visits seems to be based on Osama Bin Laden, the founder of the terrorist organization al-Qaeda, which was responsible for the September 11th attacks. Al-Qaeda reportedly took its name from Isaac Asimov’s novel
Foundation. Al-Qaeda has also made frequent use of suicide attacks. In essence, Tyler wants to find a way for the people who fly the spacecraft in the battle against the Trisolarans to be as committed to the cause of human survival as al-Qaeda militants are to their cause.
