It’s been a long time since I did a mathematical theorum, but I’m going to give it a layman’s try.
Theory: President Obama is a warmonger.
Postulate 1: South Carolina Senator Lindsey Graham is a warmonger.
Postulate 2: Senator Lindsey Graham approves of President Obama’s war posture towards Iran.
If LG = warmonger & POTUS = LG, then POTUS = warmonger.
