In many ways, this was something the U.S.A had to do, it needed a sense of closure on the horrendous events of 9/11. Many will think that this means the end of the need to worry about terrorism or more specifically Islamic terrorism. They couldn't be more wrong.
Think of Islamic jihad as Pandora's box.
When Prometheus stole fire from heaven, Zeus took vengeance by presenting Pandora to Epimetheus, Prometheus' brother. With her, Pandora had a jar which she was not to open under any circumstance. Impelled by her natural curiosity, Pandora opened the box-jar, and all evil contained escaped and spread over the earth. She hastened to close the lid, but the whole contents of the jar had escaped, except for one thing that lay at the bottom, which was Hope. Pandora was deeply saddened by what she had done, and was afraid that she would have to face Zeus' wrath, since she had failed her duty. However, Zeus did not punish her, because he knew this would happen.What OBL has unleashed is an evil ideology that cannot be dismissed by the event of his death. The evil and bloodthirsty Islamic jihad has been unleashed on the world and it will be a long time if ever at all before the evil can be returned the the Pandora's box.
