Robert Kagan in today’s Washington Post:
Imagine an Iran whose educated, inventive and highly cultured people were allowed to flourish, fully enmeshed in the global economy and society. Imagine the effect on the Muslim world and the greater Middle East of a modernizing, prosperous Iran that held regular, free and fair elections. Those who have long advocated a "grand bargain" were right to talk about the immense global benefits if Iran could be integrated into the international order. Their big mistake was thinking such a bargain could be had with benighted and virulently anti-Western leaders. But the bargain would be grand if the present government could go the way of the Brezhnevs and Ligachevs.
Regime change is more important than any deal the Obama administration might strike with Iran's present government on its nuclear program. Even if Tehran were to accept the offer made last year to export some of its low-enriched uranium, this would be a modest step down a long, uncertain road. Such a minor concession is not worth abandoning the push for real change.
