If it were me, I would have replaced the towers with bigger, taller, safer ones of the same design. That would be in keeping with the American Spirit.
But you've got to admit that these jagged towers and twisted buildings really do look like a bomb went off in the center of them. No one will ever be able to look at them without remembering what happened there.
They look like rubble frozen in time. I wonder if Liebeskind is a Dadaist...
Exactly, so while at first it may seem innappropriate, perhaps this design is exactly what is needed..
