When Dubya invaded Iraq...he really finished the job that had Iran failed to do...
Removing Saddam and empowering the Shia sect over the Sunnis.
And by "empowering" the Shia of Iraq Dubya has further emboldened the Iranians...
And why not? The US is doing Irans dirty work for them...!
The sad tale of the Iraq Adventure simply will not go away... And it could be with us for years to come...and may just have bent the stream of history in a different direction... So stupidity in high places really does have consequences...
Clearly any attack on Iran by Israel would totally destabilize the middle east...and the US in Iraq would be stuck right in the middle of the action with little hope for success.
The hope that the UN will "sanction" Iran is ill founded given that Russia and China will use the Iran issue to get even with the US over their losses in Iraq.
And clearly, the US miliary isn't big enough to invade Iran without a draft...and THAT would be the final straw for the American public.
The sheer size of Dubya's mistake in invading Iraq is even now not fully appreciated...and it's unintended consequences are even now an unknowable unknown...
