If Muslims had any sense, they would be working out their take-over in stealth, creeping along with their sharia, and adding numbers and influence through immigration. They have been very successful so far. In fact, things are going much faster than expected. If one counts open mass immigration from non-Western countries to have started around 1965, that's a tremendous amount of work they've done in less than fifty years.
But, I've always maintained that they are impatient. But, it is not them that have this restless blood, it is the Koran that mandates it. They don’t trust their stealth strategy, unlike liberalism, which has taken over whole societies without even firing a bullet.
These recent events of terror plots (read jihad) in Detroit indicates that no matter how successful they may be with stealth sharia and immigration, or the hijra (as Sam Solomon has written about), it is inadequate to think of their strategy as simply these peaceful ones. If Mohammed had been smarter, he would have told Muslims to use violence very sparingly. The funny thing is that they've waited over five hundred years to make their come-back conquest of the West. If it seems to them that fifty years are an eternity, I wonder what these five hundred years were like?
