I heard Will Rogers say this years ago:
"China is having a new war, and we are having trouble getting into it. We always have gunboats there, so if there is any shooting, why, one of our boats will get shot at, and that gives us the usual alibi. But this time it seems we only had one gunboat, and it had to maneuver around for days before it could get in the line of fire. . . . The more ignorant you are, the quicker you fight."
Now the Iranian situation presents a perfect parallel. Old Will said it all.
