Do you think this is likely?

What should we do about the possibility of such an attack?

The site, truthandgrace.com, offers an interesting take on the issue.

In the article the author discusses the destruction of Mecca and the result it might have on radical Islam.

POLITICALLY INCORRECT SOLUTION FOR ALL ISLAM, NUKE MECCA AND DESTROY ISLAM, The Case for Nuking Mecca

In the article, the author sets forth the opinion the nuclear destruction of Mecca (during the Hajj no less) would have a similar effect the destruction of Herod's Temple in Jerusalem in 70 C.E.

 had on the radical Jews of Judea. It calmed them and made them rethink their relationship to their god and to the world. Rabbinical Judaism was the result. The Romans made no attempt to stamp out the Jews - although many died. The Roman's desired to destroy the nature of the Jewish religion, and at that they succeeded.  I would argue the world is a far better place as a result. Think of how many Jews lived because they were no longer stoned to death for working on the Sabbath, or stoned for adultery. After the destruction of the Temple and its corrupt priesthood, the Rabinate brought peace, understanding, and most importantly compassion to a religion that had known very little of any of these. Would this work with radical Islam? 

What would radical Muslims do if they could not look forward to making their pilgrimage to Mecca and walking counter-clockwise around the Kaaba Stone chanting "Here I am Lord, here I am." Would they, too, have to rethink their place in the world and become more understanding of others. Would they follow in the footsteps of their cousins, the Jews, and choose to follow the intent of the law and not merely the letter of the law? Would they learn compassion?

Surely this is a radical approach, but it offers fodder for thought.
