An American member of Al Qaeda pointed to economic troubles in the United States as proof that "the enemies of Islam" face defeat, in an English-language video released Saturday.

In a half hour video message, California-native Adam Gadahn urged Pakistanis to unite against their government and U.S. forces, and taunted Americans over their economic crisis, relating it to their military interventions.

"The enemies of Islam are facing a crushing defeat, which is beginning to manifest itself in the expanding crisis their economy is experiencing," said Gadahn, in a clip of the message distributed by the SITE Intelligence Group, a Washington-based monitor of militant Web sites.

"A crisis whose primary cause, in addition to the abortive and unsustainable crusades they are waging in Afghanistan, Pakistan, and Iraq, is their turning their backs on Allah's revealed laws, which forbid interest-bearing transactions, exploitation, greed and injustice in all its forms."

Gadahn, 29, grew up in Riverside County, east of Los Angeles. He was indicted by a federal grand jury in Santa Ana in 2005 and charged with one count of treason and two counts of providing material support to a designated foreign terrorist organization.

The FBI says Gadahn moved to Pakistan in 1998 and attended an Al Qaeda training camp six years later, serving as a translator and consultant.

Gadahn also urged Pakistanis to unite and establish an Islamic state. Al Qaeda's media arm, al-Sahab, is increasingly using English-language videos to address Muslims in Pakistan who are unlikely to speak Arabic.

Gadahn warned Pakistanis to continue to fight their government which, according to him, bows to American interests.

"Someone wanted us to imagine that the same Pakistani government, which is probably responsible for the death of more Muslims in Pakistan than the Americans are, and the same Pakistan army (is) suddenly prepared to fight kufars (infidels) instead of Muslims," Gadahn said.
