If you could go back in time and stop the attacks on 9/11 from happening, would you?

I’m not sure one way or another. On one hand, it would be nice to stop those thousands of people from dying, save the World Trade Center complex, prevent the Patriot Act from being passed, and prevent our current involvement in two wars. On the other hand, it could be argued that 9/11 was just the final push in a long buildup to global terrorism. Following this line of thought, had the events of 9/11 not happened, some other event (perhaps one more heinous than 9/11) would have happened, which would have acted as the catalyst for our current situation rather than 9/11. Sort of like the Gulf of Tonkin incident…it can be argued that had those ships not been attacked, some other relatively minor event would have sparked a resolution similar to the one resulting from Tonkin.

What are your thoughts?
