there are terrorist attacks all over the world..bombings of ambassador buildings, US Navy ships run into by boats with bombs, suicide bombers in every country from Spain to Afghanistan. Most of these acts trickle down from organizations that headed by people like Bin Laden. With a powerfully influential person dead, there (in theory) will be less of that terrorism mentioned.
That is at best a future result, if anything, a man died for his actions of the past. His millions in money and influence funded terrorism and he has paid for it with his life.
And don't worry, there aren't people in the Arab world wondering where there going to get housing, food, water, or living supplies because "a" Bin Laden is dead. These men don't spread love and or help there communities as a whole. They destroy who they don't like, even they if live right next door to them and they pray to the same person. When his millions of dollars were frozen, there weren't starving communities because of it. Unless you count terrorist cells communities.
