From the Ralph Peters story noted in the NRO web briefing:

Imagine the reaction if Western agents slaughtered a hundred Sunni pilgrims on their way to Mecca. The outrage would spark incendiary rhetoric, riots and revenge killings from Peshawar to Paris. But when Sunni suicide bombers murdered 118 Shia pilgrims (and wounded almost 200 more) on Tuesday, Sunnis around the globe looked away: Shias only count as Muslims when America can be blamed for their suffering. … Where was the outcry? Human-rights groups were too busy applauding European requests for the extradition of CIA operatives (the real enemies of Western civilization, of course). Since this butchery wasn’t the fault of Americans or Brits, the Europeans themselves took no interest. American leftists, who raved that Abu Ghraib was another Auschwitz, didn’t offer a single word of pity for the Muslim victims of Muslims. All to be expected. But shouldn’t Muslims have denounced the attacks on the pilgrims? Shouldn’t such an atrocity have sparked Arab anger that transcended Islam’s internal divide? After all, those murdered Shias were fellow Arabs, not Persians. Where were the public statements of sympathy by government ministers and mullahs? Where was the noble Arab media? Where are the outraged demonstrations? … When picking allies in the Middle East, we’ve been on the wrong side of history for over a half-century. And now the Saudis are waging a propaganda campaign to convince American opinion-makers that they’re our best pals in the whole, wide world. … Well, the view I’ve seen with my own eyes – in dozens of Muslim and mixed-faith countries – is of Saudi money spent lavishly to divide struggling societies, to block social and educational progress for Muslims and to preach deadly hatred toward the West. … By the way: The two suicide bombers who killed those pilgrims were Saudis.
