Still, it would be wrong to say that Mr. Rafsanjani has suddenly become a proponent of justice, human rights and freedom.In the summer of 1999, after all, when the government crushed student demonstrations at Tehran University, he delivered a harsh sermon in the same place as he did on Friday. Back then, he blamed “enemies of the revolution” and “sources outside the country” for the unrest. He praised the use of force by the state. During much of his earlier eight-year presidency, many Iranians were executed, including political dissidents, drug offenders, Communists, Kurds, Bahais, even clerics.
