A few short weeks ago, it was unthinkable that Jeremy Corbyn, virtually unknown to the general public, would be elected leader of the Labour Party, which is for the moment Her Majesty’s loyal opposition in Parliament. The unthinkable has just happened. A man in his late sixties, Corbyn has devoted his whole career to political agitation. He has no experience in government, administration, business, or industry. He makes no secret of his idea for a Marxist program of nationalization, class warfare, and a foreign policy that turns allies into enemies and enemies into allies. Celebrating election, he and everyone in the hall sang “the Red Flag.” Isn’t this revolutionary socialism the same sort of fantasy about returning the present to the past as the Caliph and the Caliphate-shaping in the Islamic State?
