Fareed Zakaria on whether Iran actually poses a threat to the US:
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…. 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?
