This is going to get flammed to all hell given the political leanings of this website but here we go:
Turn Iran into a sheet of glass...are you kidding me? Please tell me you guys are joking about killing millions of people, and don't really think it is a good idea. Please. If you really think a pre-emptive nuclear strike is justified you need to, in the immortal words of Chris Rock, "get your *** to church" and pray God is as forgiving as some people make him out to be.
The United States as been one of the (if not THE) dominate political and millitary forces in the world for at least the past 60 years. The Middle East's political and geographic structure looks the way it does because the CIA and the US Government made it that way. WE armed Iran. WE helped to put the Shah in power and allowed the Mullahs to gain more power after his downfall. You reap what you sow.
And I am in no way, shape, or form talking about 9/11 here. We should have finished the job in Afghanistan and captured Osama. End of story. Now the millitary is spread out between 2 countries, with a 3rd on the horizon (probably will occur a few months before the next election), and no end in sight. And if you are wondering why Iran is getting so pissy, take a look at a map. The US has Iran essentially surrounded, with the norther, former USSR being the only border that is not directly controled by US forces. What the hell would you do if it was 1982 and Russia had control of Mexico and Canada. (That reminds of a great movie I need to watch this weekend...)
Before good old Rummy came into power the millitary was designed to be able to fight 2 conventional wars in different theaters at the same time. Now with our "streamlined/modern" millitary we have soldiers doing multiple tours will little rest, inadequate armor, and mercenaries handling jobs that should be done by our millitary. On top of that, politics dictate that we REDUCE troop levels, which would not be necessary if the administration had listened to its generals before this war even started and put 500,000 on the ground.
The **** we are in now has nothing to do with 9/11, it has everything to do with oil and Bush. The greatest political maneuver this administration as accomplished is convincing the public that there is a direct link Iraq, Iran, and 9/11. There is not.
