Dilip Hiro on Iran

Dilip Hiro argues that Iran 2010 is not Iran 1979.
Also he says that if the West were to push for more sanctions, this will only hurt the Iranian opposition movement:
Were the Western powers, for instance, to succeed in ratcheting up economic sanctions against Tehran through the United Nations Security Council, the opposition would undoubtedly cease its protests and cooperate with the Ahmadinejad administration to face a common national threat under the banner of patriotism.
