Bully, Bully, Bully....tsk tsk tsk.
Let's address each of your points, shall we?
1. "Actually, the Navy and Air Force are available and in great shape."
You know, as well as I do that you can bomb the shit out of an area and some wog will crawl out of a spider-hole and launch a Stinger, or its equivalent, at whatever flies by. Ya gotta have boots on the ground to hold it.
2. "Good, they'll be easy to take out but I have to ask: How can they be taken seriously if they are no threat?"
Iran poses no serious threat to its neighbors. An invading/occupying force would be another matter entirely. The Iraqi military WAS a cake-walk. The insurgency, was another matter entirely. US ground forces are not set up to deal effectively with asymmetric tactics. Some spec-op units are, but they are insufficient in numbers for the task.
3. "Except that nukes and troops are two different things. If they have nukes it doesn't matter what shape their conventional forces are in..."
Iraq doesn't have nukes.
4. "Only if we left ground troops there. As I said, we've learned from Iraq. Go in, take out the nasty regime...leave. If a new nasty regime takes over, do it again."
Go to any 12 step meeting, and you'll learn that doing the same thing over and over again in the expectation of a different result is a definition of insanity.
5. "Yeah that Reagan was a hell of a diplomat!"
Not so much. A doddering fool, yes, but he at least had some competent people in his cabinet, which is far more than cam be said of the current occupant of the Oval Office.
6. "I remember Iran's form of diplomacy....'take hostages, then blackmail' "
Didn't much work.
7. "We'll know just as soon as the mushroom cloud pops up....just like North Korea!"
Had the Bush administration allowed implementation of the plan started on Goatboy's watch, North Korea would have ceased to be an issue for the last 3 0r 4 years. Instead, Chimpy axed the plan, NK had the intervening years to develop and test their bomb, and now, Chimpy and Co are implementing the plan set out by Goatboy and Co. Only now, NK has nukes. And didn't Condimima say something about mushroom clouds in the run up to Iraq? We see how that turned out.
8. "Of course, Iran hasn't been rattling anything. I suppose too you agree that Israel and its people should be made to disappear."
Not at all, but a fair and equitable resolution of the Israeli-Palestinian conflict would go a long way to help defuse the tensions in the region.
9. "Nothing to gin up, they just go at each other naturally or are you blaming Bush for a centuries old conflict?"
In order to undermine Iran, Chimpy and Co are backing Sunni insurgents, many with al Qaeda ties, in Lebanon. These clandestine activities are aimed at stirring up simmering enmities between Sunni and Shi'te, with the administration taking the Sunni side, which just so happens to be the Saudi side....Which also complicates relations with the Shi'ite government the administration installed in Iraq. Nothing like a little regional destabilization to make for a dismal presidential legacy.
