On Wednesday, a series of explosions rocked Mumbai, India. At least 21 people were killed and more than 100 injured in what is at least the third major terrorist attack in the city in recent years. What can we learn in the immediate aftermath of this attack? What kind of threat do domestic radicals pose to India? What could India learn from the U.S. about preventing terrorist attacks? And does this suggest that recent predictions of Al Qaeda’s imminent demise were premature? We ask Dr. Walid Phares, terrorism expert, adviser to the U.S. House Anti-Terrorism Caucus and author of “The Confrontation: Winning the War Against Future Jihad”.
