One group of Washington-based pundits and exiled Iranians wants to push the United States into increasingly hostile and direct confrontation with the Islamic regime, using coercive diplomacy and even military pressure if necessary. This group also wants to encourage demonstrators inside Iran to rise up and confront the regime as quickly and boldly as possible, even if this would prompt violence, revolution or civil war. Some members of this group -- following in the footsteps of the Iraqi exiles and U.S. policymakers who favored installing exiled banker Ahmad Chalabi as leader of Iraq -- are determined to handpick Iran's next leader. Their choice is Reza Pahlavi, the eldest son of the last shah to rule in Iran.

A second group in Washington is pushing for a completely different U.S. policy toward Iran: detente. Increasingly, Iranian hard-liners have hinted that they might be willing to restrain Islamic radicals based in Iran who are stirring things up in Iraq. But in exchange, they've suggested, they would want guarantees that the U.S. will not support opponents of the Iranian regime. Desperate to hold onto power, Iran's leaders seem suddenly willing to deal with the U.S. in exchange for stability.

These proponents of engagement inside Iran have allies in the U.S. Since Hashemi Rafsanjani was elected president of Iran 15 years ago, a group of U.S. scholars, retired diplomats and businessmen (especially oil company executives) has acted as de facto lobbyists for the Islamic regime. They considered Rafsanjani to be Iran's great hope: a "moderate mullah" who wanted rapprochement with the West. When reformer [Mohammad Khatami] was elected to replace him in 1997, they changed horses, but not their recommended strategy of engaging with the existing regime.
