Hate to say it Tom, but in this case FQ is basically right. Saddam was seen as a "stabilizing" influence in the Gulf for a number of years. He, through Iraq, kept Iran in balance with the other nations, similar to the US and USSR in the "Cold War." Just enough force on both sides to have them look long and hard at making a push. Sure we had to pop him in the nose periodically to stay in line, with inspections and keeping things within the Parallels, but it really wasn't a big deal and was great training.
With Iraq destabilized Iran doesn't have any reason to remain covert about it's desires to rule. The US and Russia aren't going to do anything about it. Israel is the only ones that have anything to loose, and they aren't getting any support from us.
That's part of what I'm getting at, just because he "was seen as" doesn't make it so.
August 1991 proved that the people who did the seeing were dumb asses.
Not to mention that the earlier need to reflag oil tankers proved that the "Iraqi counter" was worthless.
We could eliminate all this trouble if we announced a major policy speech on relations with Iran and fired one missile, IIRC the sub launched MIRVs carry ten warheads, that's one for the location of the Iranian leadership and 9 for their nuke sites.
Problem solved and the whole rest of the world sits back and reevaluates their position, China Russia, and India have their own issues that could benefit from such action ( most being made worse by Iran ), Chechnya, Pakistan, and N Korea for starters. so they may bitch in the UN but they won't DO anything.
As for the rest of the world, they need us a lot more than we need them.
In order to stave off the bleeding hearts I will also point out that while a nuke strike would lead to civilian casualties, history has shown that the results are far less costly than waiting until conventional war is unavoidable.
Because of increased accurracy, and the fact the targets would most likely require ground bursts against bunkers, lets say there are 100,00 killed , military and civilian.
That's 1/10th the losses to just the military in the conventional war with Iraq, and it happens with destroying either nations economy or infrastructure which leads to faster recovery and normalization of daily life.
