I think all muslim (shia & sunny) must be killed. you cannnot convert them that why they must be killed. but question is that how.... i tell you. they will killed only one way: you have to killed them by mass level. mean use Biological weapons like Saddam hussain use- chemical weapons. why muslim should killed because their kaum is very very dengerous for human man kind at that time when they will be in a position of majority that time they will finish all other kaum like carrot. so must act before that.
