Below are three examples, but first the customary disclaimer: I'm not excusing any violence that American policies may have helped cause and I'm not blaming America. But when American policies have bad side effects, Americans need to talk about them.

[1] Drone strikes. Obviously, President Obama doesn't want to say anything bad about the gobs of strikes he's authorized. Neither does Mitt Romney; if you're going to spend your whole campaign calling Obama a hyper-apologetic girly boy, you can't turn around and complain that he kills too many people! But American drone strikes--which seem to always target Muslim countries, and sometimes kill civilians--are famously unpopular in the Muslim world. Note which countries tend to cluster toward the bottom of this graph from the Pew Global Attitudes Project. And watch the one-minute-clip below of my conversation on BhTV with Robert Becker, an American who lives in Cairo, taped after the protests had started. I asked him to list the most common Egyptian complaints about America, and here's what he said:

[2] Israel-Palestine. That's the second issue Becker mentions in the video clip, and it is also cited in a recent Atlantic piece by Middle East expert Steven Cook of the Council on Foreign Relations. Again, don't expect to hear about this from Romney or Obama. During an election campaign, especially, neither man wants to dwell on the downside of America's essentially unconditional support of Israel even as Israel pursues policies that violate both international law and basic principles of justice, such as the expansion of settlements in the West Bank. But rest assured that the Israeli-American relationship gets plenty of airtime in Muslim, and especially Arab, nations. And, while some of this assumes the form of wild conspiracy theories, the core fact that American support helps sustain highly objectionable Israeli policies is not a figment of anyone's imagination. Neither is the fact that when President Obama did try to get Israel to freeze settlement expansion, he encountered so much blowback in Israel and America that he had to give up.

[3] American troops in Muslim countries. Though American soldiers have left Iraq, they remain in Afghanistan. Noting the downside of this fact doesn't fit into either Obama's or Romney's game plan as they try to out-hawk each other. But, while they stay silent, there are people who are happy to talk about American troops in Afghanistan: Jihadi recruiters. And the reason is that they know this subject strikes a chord among young Muslim men who for various reasons (including local ones such as unemployment) are unhappy campers to begin with. This demographic played an important role in many of the protests last week.

The three grievances I've listed (and there are others) aren't wholly unrelated to that horrible YouTube video. They're interpreted by some Muslims as evidence of American contempt for the Muslim world, and the video was taken as yet more confirmation.
