One clear aspect of Mohammad’s life was that he conquered when he had power and was wise enough to bide his time when he was weak. In this way he gives the infidel world a means to control the spread of Islam.
Islam should be confined and kept weak lest they spread and attempt to invoke the prophecy that they are the true religion into the part of the world that does not believe in Sharia.
In this aspect, I believe Trump has the right idea.
Then how do you keep them weak? Immigration controls? Arming competing factions? Destroy oil facilities that we can fill?
