Cairo, Egypt ? Cornered in a cave somewhere in the wilderness where Pakistan and Afghanistan meet, Osama bin Laden and his top generals may be cut off from fighters and money, yet they can still strike with angry words and ideas.

Their ideology — rooted in generations of Muslim resentment of the West and aired in a series of audio- and videotapes, on Arabic television and over the Internet — is creating an al-Qaida legacy of terror that has spread around the world, analysts say.

Al-Qaida “is as much an organization as it is an idea, and that idea is self perpetuating,” said Magnus Ranstorp, director of the Center for the Study of Terrorism and Political Violence at St. Andrews University in Scotland. “What is al-Qaida? We make it synonymous with its leadership, with bin Laden. But it’s more than that.”

The latest audiotape attributed to bin Laden aired Saturday on the Arab television station Al-Jazeera, featuring a call on young Muslims to fight a holy war against American forces in Iraq and threatening suicide attacks inside and outside of the United States.

Also Saturday, an al-Qaida-style recording surfaced on the Internet featuring what is described as audio of militants launching a suicide bomb attack in Saudi Arabia in May, killing 26 people in a Western housing compound. A speaker dedicates the attack to bin Laden and the audio includes what appear to be old statements from him calling on Muslims to wage a holy war on the United States and its allies.

In recent years, Islamic militant groups around the world have adopted al-Qaida’s strategy of suicide bombings. Groups that once may have been more interested in toppling the government in Jordan, Indonesia or the Philippines also have adopted al-Qaida’s internationalist view that the enemy is the West in general and the United States in particular. Muslim resentment also is growing about Israel’s treatment of Palestinians.

During the Indonesian trial of Imam Samudra, accused mastermind in the 2002 Bali nightclub bombings that killed 202 people, most of them foreign tourists, prosecutors introduced testimony from another alleged militant who said the Bali bombings were planned after calls by bin Laden for terror strikes on Americans and other Westerners.

In September, when he was sentenced to death, Samudra shouted, “Go to hell, you infidels!” and threatened President Bush and Israeli Prime Minister Ariel Sharon.

Dia’a Rashwan, an expert on radical Islam at Egypt’s Al-Ahram Center for Political and Strategic Studies, said the United States may have played into bin Laden’s hands by moving into Iraq to topple Saddam Hussein. Bin Laden said the United States wanted to control Muslim land, and now U.S. troops are doing that in the heart of the Arab world.

In the minds of some Muslims, “Bin Laden said theoretical things, but now the theoretical things have become reality,” Rashwan said.
