Dubya's record on "finding" WMD is checkered....to say the least.
ANY ATTACK ON IRAN WOULD BE A DISASTER...that would make Dubya's current troubles pale in comparison.
Iran is bigger than Iraq....by far. Iran has not been crippled by sanctions and prior war, (Gulf War I) as Iraq.... Iran is a far more cohesive nation.
Europe and Russia are doing business with Iran....and they will not take kindly to another "American Intervention" in their business affairs..... Remember Iraq's oil contracts?
Furthermore, Dubya is broke and has no army to spare... Where is the money going to come from... China?
Dubya's disasterous tax cuts have put American War Finances in the hands of foreigners! If China says it's OK to invade or bomb Iran....fine.
Remember wars have a bad habit of trashing the bond market eventually. And Dubya is getting real close to that point now.... The dollar is weak. And the bond market is levitating...miraculously. So far......
And of course, Dubya's "new chums" the Shia of Iraq are co-religionists with the Shia of Iran..... And the beat goes on.....
Any attack on Iran would be historically similar to Hitlers attack on Russia during WWII.....Hurbis on the verge of total madness......
TWO FRONT WARS ARE SIMPLY NOT WINNABLE.
