Whether Jesus was "interested" in drawing a distinction between tolerating a slap in the face and tolerating a blow to the left side of the head with a knife is irrelevant.  The fact is, there is a distinction, one so great that they differ not merely in degree but in kind.  No one rationally takes an admonishment to turn the other cheek as a command to let a man armed with a knife stab you on the right cheek after he has stabbed you the first time on the left.  One could reasonably take Jesus at his LITERAL word when he tells us to let pass a relatively minor insult, such as a slap in the face.  Not so in the case of the man who has just stabbed you and is coming at you again.  You draw a comparison where common sense tells you to see a conspicuous contrast.  Thus, Jesus's telling us to turn the other cheek says nothing thing about the morality of war fought in self-defense. 

That Jesus has a soft heart for the weak, helpless, and persecuted does not argue in your favor.
