Whereas proposals for high-rise developments in Jerusalem have prompted a worldwide outcry and the Taliban's demolition of the Bamiyan buddhas was condemned by Unicef, Mecca's busy bulldozers have barely raised a whisper of protest.
Some holy places yet remain beyond the reach of the bulldozers, however. For it to remain so, the success of the mission in Iraq is essential (the issue of how we got involved in Iraq aside). That's the sole reason that I don't support an otherwise airtight argument for calculated withdrawal. The planned cut and run that we will inevitably see before 2006 however is far worse concern.
I had some comments on Bamiyan earlier. FWIW, I count their destruction as a tragic loss to humankind's heritage. But hardly the most tragic loss.
