A credit to Lincoln and his peacemaker policy to “let ’em up easy.”

[DiogenesLamp]

Well since they didn't have the moral or legal right to invade and kill people in the first place, then "let them up easy" is probably the least thing a murderous invader can do to attempt to make amends.

But how about this? Don't invade and murder people in the first place! Then you won't have to let your victims up easy.
