So... now what?
The big boss is dead. Credits roll, triumphant music plays and the US administration returns the civil liberties it took away after 9/11. It ends unwarranted wiretapping, off-shore abductions, violent interrogations and will ceases funding terrorists. A peaceful time of prosperity and economic growth ensues. Relations with the middle east improve.
Obama uses this card to get re-elected, new, harder "anti-terrorist" laws are implemented, the middle east relations continue being deliberately undermined and the US continues selling arms to terrorists. You think the people who helped Osama and Saddam rise to power will suddenly have a change of hearts? Terror is too fucking damned useful for that to happen.
"The dark, ugly terrorists are coming to get us. Are you afraid, citizen? Are you afraid enough?"
