Iran jingoists get a wag of Fareed Zakaria's finger:

Iran has an economy the size of Finland's and an annual defense budget of around $4.8 billion. It has not invaded a country since the late 18th century. The United States has a GDP that is 68 times larger and defense expenditures that are 110 times greater. Israel and every Arab country (except Syria and Iraq) are quietly or actively allied against Iran. And yet we are to believe that Tehran is about to overturn the international system and replace it with an Islamo-fascist order? What planet are we on?
...
We're on a path to irreversible confrontation with a country we know almost nothing about.

But hey, when has that ever stopped us?
