U.S. Presidents and Those Who Kill for Them by Laurence M. Vance

But what kind of a man would kill someone he didn’t know, who had never harmed or threatened him, his family, his friends, or anyone he knew for someone he didn’t know, who didn’t know him, and had never been harmed or threatened by the person he wanted killed?
And even worse, who would do such a thing at a moment’s notice, without giving it a second thought, laugh while he did it, brag about it afterward, and then expect to be lauded as a hero?
It pains me to say that the answer is a soldier in the U.S. military.
