Leading commentators and diplomats have been pondering for quite some time why the Iranian leader is not prepared to act against the revolution in a major way. The “China model” could be applied, a brutal, fast, and extremely violent strike against the opposition. According to conventional wisdom, tyrants will use all means to eliminate their opponents. So why haven’t the mullahs adopted Chinese methods?
The PRC's method is to dispatch a couple of divisions of the military, take prisoners, execute them, and announce that going forward, there will be no more dissent.
It works pretty well.
...I also heard another reason, which, if true, would be the main reason. There are serious doubts about the military itself. The army and parts of the Revolutionary Guards (abbreviated as RG) would, under those circumstances, choose the side of the opposition and the people. The military power of Khamenei would be broken. This, however, was speculation without proof.
Now there is evidence to support it. On December 10, a statement signed by a number of officers and commanders of the Iranian army was released. The regular army of Iran had not been involved in the suppression of the population.
In the letter, a number of regular-Army and Air Force officers wrote that
'...the weapons of the army and RG are to be used to protect the nation: “When we fought together, we could never suspect that parts of the RG would ever use its weapons against the people.”
The last section of this brief but powerful statement will surely immortalize these brave officers: “The army is a haven for the nation and will never want to suppress the people at the request of politicians. We shall remain true to our promise not to intervene in politics. But we cannot remain silent when our fellow citizens are oppressed by tyranny.”
