If all the Allies do is pound Afghanistan into even more rubble and don't broker a long term workable peace for the Palestinians and Israelis (the root of most if not all of the instability in the region and hence the world), then I fear that this uncertain and unstable situation will last for many years to come. The consequence being that the travelling public will remain too scared/nervous to travel.
There is still hope for all wannabes (including me) - let's see what happens.
