Murray Rothbard has written a poignant article in 1979 in The Libertarian Forum entitled "The Iran Threat," which I hold is still relevant even for today as we understand our history.
The threat in Iran is grave, even potentially cataclysmic. But that threat is only secondarily the danger to the 62, now 49, American embassy employees imprisoned in Teheran. The main danger is a disastrous war, to be launched by a furious and petulant United States against the people of Iran. For the really scary thing about the still continuing Iranian crisis is not the Shiite zealots led by the venerable Ayatollah Khomeini; it is the barbarous emotions welling up in the breasts of the American people.
