You remember a few months back when a pastor in Florida threatened to burn a box of Qurans. It caused an international incident, with world leaders contacting the US President, the US Secretary of Defense had an emergency meeting, the FBI met with the man, ecumenical press conferences from religious leaders begging the man to stop, a gaggle of satellite TV uplinks were parked across the street, the US General in Afghanistan said soldiers would be killed. On and on it went, dominating the news for many days. In the end, the pastor changed his mind and did not burn the Quran.
However, it appears that Muslims didn’t hesitate. They burned a Coptic Christian man to death in Egypt when it was rumored he had a relationship with a Muslim woman (see the story here). In another Egyptian town, the Muslims burned ten homes when they heard a rumor that a Coptic Christian was spotted with a Muslim girl (see the story here). Muslims in Indonesia burned Protestant and Catholic churches (see the story here). In Pakistan, a woman was sentenced to die for “blaspheming” the Muslim prophet, with no more evidence other than an accusation. In Iran, a Christian pastor was sentenced to die for complaining about school children being forced to read the Quran (see the story here.)
As far as I know, not much happened with these incidents. I doubt that any heads of state contacted anyone. Most likely the Secretary of Defense never had any meetings about these incidents. No ecumenical news conferences, no TV trucks.
So it seems that it is an international incident for an American to burn a Quran, but when Muslims burn people and people’s homes, no one seems to care.
