Chances are "Option A" will not pass Security Council vote due to China veto.
This leaves "Option B" which, too many, might seem understandable...especially to Isreal. Mr. Obama will likely not sanction an airstrike; he will simply turn his back. Once Israel decides to "go", no one/nothing can stop them...especially with Mr. Netanyahu at the helm. I believe the American term is "Hawk".
This might seem "OT" to some---it is NOT.
China./U.S. economic relations could prove catastrophic re existing foreign debt structure. Oil prices would likely increase inordinately.
IMHO
