Iran was becoming Westernized until the Shiites, under "ayatolah" Khomeni, took over.

You should read more about the history of the Iranian Islamic revolution. It did not have much popular support; only 25% or so of the population was for it. Most people supported the Shah, who was friendly with the US. Without the help of the KGB, the revolution would never have succeeded.

Iran is nearly 100% Shiite, and today as before a large majority is against the theocratic government. The Shah's son is also a highly popular figure there.

Iraq's Shiites are of a simlar disposition. On the whole they are not prone to radicalism and anti-Americanism.

... the Iranian Islamic revolution ... did not have much popular support; only 25% or so of the population was for it.

      And it made no difference at all how many were for the Islamic revolution and how many were against it. 

In Afghanistan, the U.S. is paying the salary of the head of the Supreme Court, who is trying to forbid the broadcasting of female vocalists, has embraced flogging, amputation, and stoning, and threatened to "behead" non-Muslims who refuse to submit to his version of Islam. Since he views the law as divinely ordained, any critic can be charged with blasphemy, which has already happened to one cabinet minister."

      And if the U.S. follows the same functional policies (regardless of the rhetoric) in Iraq as in Afganistan ... the disposition of the typical Iraqi will be irrelevant.
