More than 17,000 people in 17 nations were interviewed from April to June for the survey, the sixth multination poll by the non-partisan group since 2002. Some results were released last month.

Among the new findings:

• Support for suicide bombings and other acts of violence in defense of Islam has dropped since 2002 by 34 percentage points in Lebanon, 12 points in Indonesia and 8 points in Pakistan. The exception to the trend is Jordan, where support increased by 14 points, to 57%.

There are higher levels of support for suicide bombings that target Americans and their allies in Iraq, though they also have dropped. About half of Muslims in Lebanon, Jordan and Morocco said those attacks were justified.

• Confidence in bin Laden has fallen by double-digit margins in Indonesia, Morocco and Lebanon since 2003. In Lebanon, only 2% now express confidence in him.

The al-Qaeda leader is viewed most positively in Jordan and Pakistan, where more than half say they have confidence in him.

• Most Muslims believe Islam is playing a larger role in their national politics and see that as a positive development.

In nine Western nations polled, fears about radical Islam were tied to perceptions of Muslim communities within those countries. Resident Muslims were seen as having a strong and growing sense of Islamic identity, a situation most of those surveyed saw as a bad thing.

Even so, in the United States and most Western nations majorities said they had favorable views of Muslims. Those in predominantly Muslim countries had mixed views of Christians and very negative views of Jews.
