Wishful thinking, amigo. It would have been the smart play a lot earlier. The current forward momentum for a tougher foreign policy is almost nonexistant. As things stand now, there's enough discontent over the war, and specifically the war as waged by the current administration, for the Dems to resist the President at will.
Iran will correctly assume that the American people are tired of foreign conflicts, and aren't looking to start trouble with a country even more volatile than Iraq. The Dems will correctly assume that so long as they don't overplay their hand, they can force the President to assume a less aggressive stance and get away with it. President Bush is on thinner ice than ever before. That's bad footing to be on for tackling a task like Iran.
Hell hath no fury like a President who doesn't have to face the voters.
The Dems won't overplay their hand for awhile, but trust me, they will eventually. It's the IRANIANS I'm counting on. They will overreach: this election guarantees it.
War will come to Israel first, from three sides. You will be surprised at our response, I suspect.
Be Seeing You,
