Azam Amir Kasab, a 21-year-old man from Pakistan, is the only terrorist police captured alive after the Mumbai massacre ended. Details from his interrogation have been leaked [1], and they reveal a chilling picture of a nightmarish tragedy that could have turned out even worse. After playing dead in order to survive, Kasab told police:

• The synchronized attacks were planned six months ago, and intended to kill 5,000 people. So far the death toll stands at around 200.
• The group of 10 terrorists had planned to blow up the entire Taj Mahal hotel, but were unsuccessful.
• The would-be attackers posed as students on a trip to Mumbai a month ago to acquaint themselves with the city.
• The men specifically targeted "whites," especially British and American citizens.
• Kasab said he belonged to Pakistani terrorist group Lashkar-e-Taiba, which has denied involvement.
• Kasab said he was told to "kill to my last breath."

As those impacted by these appalling events recover and mourn, international players urgently want to reduce the probability of a confrontation between India and Pakistan [2]. Depending on how things play out, India might take a US approach: if one country can't deal with its terrorists, then another country has a right to do something about it.
