What you stated is absolutely correct.
Tehran's ruling despotic butchers are the most fanatical of "Jihad-O-Holics". In this jihadist enemy's demented method of viewing the near future, if they do not instigate a global war to begin the "cleansing the world of infidels" their Mahdi, the "hidden 12th Imam", will not return and finish "jihadic justice".
The market savvy Ahmandinejad régime knows the quickest method in bring down the West is by totally panicking the energy markets. Unlike Saddam, this bunch will not allow themselves to be taken prisoner. Ahmandinejad has already ranted on about blowing up Iran's huge oil and natural gas reserves in order to prevent Islam's "enemies" from securing Iran's portion of the "treasure of Allah".
These frenzied, Mohammedan, Shi'ite lunatics also clearly fathom how world-wide financial markets would react, the total trader pandemonium ensuing rapidly at viewing the vast oil fields of Iran, Saudi Arabia, Kuwait & other Gulf based OPEC exporters going up in flames, attacked on the mullah's orders, not to mention activation of global sleeper cells - unless we beat them to the punch!.
The longer we wait in blasting the Iranian clerical dictatorship out of power, the higher the risks of the unthinkable sinking the entire Western world's interconnected, oil-based, economic system.
This is like 1939 all over again. Have we not learned anything?
