Glass is glass. It will break if it's hit with enough force. And remember that the original WTC towers were designed to and were able to withstand the force of jetliners crashing into them at full speed, and also stay up for about and hour or so. Its failures weren't just that it collapsed (because of the intense heat's effect on its steel structure), but that its core was poorly shielded from the force of the airplane going through it. The core housed all of the emergency stairs, and the thousands who perished did so as a result of the lack of access to those stairs to safely reach the ground.
The new 1 WTC has been designed to withstand the force of jetliners and still stand, just as its predecessors were able to (duh). But it's main safety feature is its high-strength reinforced concrete core, which will withstand the force of the airplanes, protect the emergency stairs to allow the occupants to reach the ground safely, and resist the intense heat and help keep the overall structure from collapsing outright.
But it seems more like you're wondering if, after the event of another air attack (unlikely in this day and age), whether they could simply clean up the glass and debris, patch up some walls and install some new steel, and put up some new curtain wall. I wondered the same thing back in 2001, 30 minutes after the planes hit the towers. Ultimately, the answer is no - the building would be too dangerous to be occupied. It would have to be demolished piece by piece, and a new building would have to go up.
But in the end, the key here is saving the lives of the building's occupants. It always has been.
