There are 1.3 billion møøselimbs on the planet.
Our very survival requires that we kill n møøselimbs. Where n is a number between 0 and 1.3 billion. It is defined as the number necessary to kill for the remainder, 1,300,000,000-n to forswear violence as a means of religious debate.
WE don’t set the value of n.
THEY set the value of n...
In less mathematical terms:
We need to break the will of militant islam. This is something 1300+ years of bloody conflict with civilization under varying degrees of Queensberry rules has failed to do.
We need to kill enough of their people and break enough of their stuff that the rest decide that murdering or enslaving everyone who isnt muslim enough isnt a good idea.
Since this is the #1 core value of their faith, this may end up being all of them.
And yes, although I would much prefer that they forswear violence as their holiest sacrament, Im quite OK with eliminating all who will not.
