To avenge the events of 9/11, as well as extend the influence of capitalism and democracy. He also wanted to investigate/confiscate some nuclear warheads in the Middle East, as well as quell as many evildoers in the Arab nations as possible. As to the evildoers, he wanted to trace the attacks of 9/11 to a specific location in the Middle East, and stop Al Quaida as well as Osama Bin Laden, and rescue the victims of terrorism. He also wished to aid the poor people in Iraq and Afghanistan with food and supplies. He did want and has beefed up the airport security nationwide, giving more stability to the airline personnel with firearms/handguns, as well as heighten the attention given to all who leave the country and all who come into the country from the Middle East.
