During his visit to New York this week to address the UN General Assembly, Iranian President Mahmoud Ahmadinejad is scheduled to go to Columbia University to address faculty members and also to meet with a group of American religious leaders. His arrival was preceded by weeks of commotion and dispute: should Ahmadinejad have been allowed to visit ground zero? Should Columbia have agreed to host him? Should he even have been granted a visa to enter at all? In a spasm of infantilism, Republican presidential hopefuls and the right-wing punditocracy have seized the occasion to demonstrate their toughness, decrying the Iranian leader's mere presence on US soil.
