I disagree, I think rebuilding the WTC bigger and better will show the strength of America's will and resolve. What would be more frustrating for those who sought to bring down the building to only see the buildings be resurrected in grander fashion? I agree that a memorial should also be put in place to commemorate those lives that have been lost in this tradgedy.
If we do not rebuild than, Usama Bin Laden (If he commmanded these acts) would have gotten his way. Ever since the first bombing of the WTC he wanted to bring both buildings down, we cannot let him win.
I say we rebuild the WTC and in typical American fashion make them the largest most technologically advanced buildings in the world. We don't physically need a middle finger, they will stand as a symbol of American prosperity and capitolism.
