This is exactly what happens in the Vatican on Christmas and in Jerusalem on Yom Kippur. Exactly:

Filled with the spirit, Iranians chanted anti-US and anti-Zionist slogans at holy event. Iranian Republic News Agency reported: Disavowal of Pagans ritual ended in this sacred desert on Tuesday by issuing a five-article final resolution which stressed on unity among all Muslim nations. The ceremony was attended by a huge group of Iranian pilgrims who chanted anti-US and anti-Zionist slogans.

The Supreme Leader of the Islamic Revolution Ayatollah Seyed Ali Khamenei offered this blessing to the Hajj pilgrims, via IRNA: "Today, the treacherous enemies of the Muslim Ummah are the organizers of the hegemonic centers and expansionist and aggressive powers which consider the Islamic awakening as a great threat to their illegitimate interests and their oppressive domination over the Muslim world. All the Muslim nations led by their political and religious authorities, intellectuals and national leaders need to form a united Islamic front against this invading enemy with full strength.

You know what's so weird about this? We were totally convinced by the assurances of foreign policy elites and think tank sophisticates that Sunnis and Shiites hate each other way too much to cooperate against the West. They're very different you see. Not so different that they won't funnel money to each other and cooperate on international terrorism. But still very different.
