I agree about the 9/11 bit... the whole song seems to be like from the perspective of someone greatly affected by it.
The song sounds like its about how we've been apart of a large world, doing our own part and feeling alone and full of dispair. However, 9/11 happens and suddenly we realize that we each do our own part in keeping the world together and we no longer feel alone because we've all been affected by it ("we'll build again, rebuild again").
