Brilliant analysis! Our bag of options are clear.
We live in very interesting times where the Saudis have "radicalized" 80% of US mosques with their cash and wahabbi brand of salafyism (see here and here ) and have done the same in many isamic countries, constructing beautiful enormous marble cladded mosques, engaging in their dawah and controlling zakat collections. If anythings becoming remotely close to claiming the title of "mainstream" islam within the many sects and divisions, this may just be it.
They're on to a head start and the liberals will be there to help our enemies.
We have already waited too long to act, Saudi Arabia is a terrorist state and has even been raising funds in public to reward suicide bombers. Plan B sounds good to me.
