Or would the Jihadists just go doubly berserk?
As for jihadists taking over America, no way. The Hispanics will never let it happen.

The only example we have to go on is the destruction of the Jewish Temple. This got the Jews pretty riled up, but it didn't destroy their religion, despite its centrality to it.
One can only hope that the nuclear annihlation of the black rock and the great Mosque in Mecca would at least wake some Muslims up to the falsehoods they are laboring under. Others, undoubtedly, would go suicidally nuts, like the Jewish Zealots (Bar Kochba and all that).
Someone posted here the "Five Pillars of Islam", one of which is to make the Hadj pilgrimage at least once to the holy of holies - the black rock - in Mecca. If that's gone, then the basis of the faith is gone. Kind of like the great Wizard of Oz being revealed to be merely the little man behind the curtain. But, as you correctly observe, we are dealing with fanatics who are by definition irrational. It's unlikely they will think this through.
