Interesting discussion on this mornings "Meet the Pricks".
One theory put forth is since MCCain is likely only looking for his four years of grandeur, he could be a real renegade once he is sworn in. That could be a good thing. A return of the old McCain "maverick"?
The scary part is, given his hair-trigger temper and Hawkish mentality, he also has nothing (politically) to loose if he should decide to obliterate another country. Iran was mentioned.
(IMO Reagan should have obliterated them as soon as we got the hostages back.) But in any event, the old addage about doing battle with a skunk rings true. It doesn't matter who wins or loses, everybody ends up stinking.
IMO unless Iran forces everybody's hand, we should avoid an all out war due to the economic catastrophe it would cause for all of us. Of course, all bets are off if Iran stupidly confronts Israel with a serious do or die threat.
