Washington ? Top U.S. counterterrorism officials Monday said al-Qaida is “imploding” and that its violent tactics have turned Muslims worldwide against the organization.

“Absolutely it’s imploding. It’s imploding because it’s not a message that resonates with a lot of Muslims,” said Dell Dailey, the State Department’s coordinator for counterterrorism.

Al-Qaida still remains the most dangerous threat to the United States. But of growing concern are organizations like Lebanese Hezbollah and Hamas, which combine social services, local governance and national politics with extremist attacks, said Undersecretary of State James Glassman.

Vastly more Muslims than Westerners are killed by al-Qaida car and suicide bombs, particularly in Iraq, where local tribes have largely turned against al-Qaida in Iraq in the last two years. Extremist violence claimed more than 9,500 civilian victims in Muslim countries in 2007.
