If my replacement is 'a real yes man' then 'God help us'

It's possible that he tried to take my advice and drop a series of hydrogen bombs on Mecca and one on Medina. With enough hydrogen bombs in succession at just the right interval, the Black Rock would be atomized. Then we could fill the crater with pig excrement. Nobody is going to walk in circles around that. The radiation would make short work of anyone who went near, and the stench would discourage anyone with a nose.
This would effectively be the end of Islam.
The two holy sites of Mecca and Medina are essential to Islam. Without those it is purely theoretical without a valid practice. Bowing to Mecca would become perverse.

The problem is the continuation of the policy of mutual assured destruction (M.A.D.)
Younger folk aren't taught about this in public education, anymore. It is still in effect. If any country uses nukes against another country, the other countries that have nukes are obligated to use them against the offending country. It is why nobody has used nukes since Hiroshima and Nagasaki.
So using nukes on Mecca and Medina would have to be done secretly, where it couldn't be shown that we did it. Submarines might be able to do that.
We could say that France did it. France would deny it and accuse us. Then we could say that maybe the Chinese did it. The Chinese would deny it. Then we could say that maybe the Russians did, heck we didn't do it.
