Believe me, I understand everything that you are saying. the fact is though not not all 1 billion Muslims believe that “pillar of faith”. Given that there is no chance of the West “winning” by killing all 1 billion Muslims, then the answers come down to:
a) Islam is “reformed” from the inside (i.e. through the ‘moderates’)
b) the world submits to Islam and it’s the end of civilization
“Given that there is no chance of the West winning by killing all 1 billion Muslims”
Oh come on, we haven’t even TRIED YET!
