The Iranians thanks to their support of Assad have stationed mobile Chinese made short range ballistic missiles in forward positions in Syria. If Israel attacks Iran, it will suffer a devastating counterattack from these missiles. The Iranians have also fortified the Persian Gulf with shore to ship missiles.If the big blue water carrier groups operating in the narrow Persian Gulf are engaged, the US Navy faces a debacle worse than Pearl Harbor in less than 15 minutes. Since Obama has made it abundantly clear that he has no intentions of attacking Iran, he ought to withdraw those ships from harms way.
If (heaven forbid) such a scenario like that happened, the wun would simply say something along the lines that it was a budget reduction effort and no replacements will be built and then go on another world wide vacation and apology tour.
