I think Iran and the GWOT have been "job one" since "day one" with President Bush.
Iran is a good sized country with a large army and a sophisticated and educated population. A war with the premier perpetrators of Islamic terrorism is no small feat. But, right now we have a combat toughened military whereas the last combat Iran saw was sixteen years ago. We won't have to cover our flank on the West worrying about Hussein's Iraq and in fact now have bases there along with some 300,000 newly trained Iraqis many of whom hold some fairly serious grudges against Iran. We have bases in the North in Turkey, new bases in several of the "???-STANS" of the former soviet bloc to the North, Afghanistan with current U.S. bases to the East, a friend in the President of Pakistan to keep them on the sidelines and India who would love to exert more influence in central Asia. Put a handful of carrier battle groups to the South and Iran is in fairly sh?t shape.
In conclusion, I don't think I or President Bush have missed the point at all.
