Hitler didn’t have numerous sects who all hated each other because each believed the other was not fit to live.
“Hitler was not defeated by his own people, neither were Ho Chi Minh, Lenin or Fidel Castro.”
My point being that none of the internal “resistance” forces were able to overthrow the ruling regime. If we (or europe) allow Islam to do what they want they will rule until invaded by another force.......
which there are none other on earth now.
