terrorist attacks

I just wanted to put my two cents in about the latest attempt to bomb the world to death by extremists acting as terrorists. First of all, whyt can't we all just get along? I mean, the world never used to be as violent as in recent years with 9/11. Anyway, these latest attacks make me think twice about flying in an airplane. I also fear what will happen when the world comes to see the 2010 Olympics. Is my backyard safe, or will it be like WWIII? Tell me about your travelling experiences since 9/11.
