STRATFOR: Strategic Forecasting Inc. In its weekly series of articles has discussed the motivations behind the attacks in Mumbai, I think its definitely worth reading to better understand the issue with a more neutral perspective without getting embroiled in a heated Indo-Pakistan debate
Last Wednesday evening, a group of Islamist operatives carried out a complex terror operation in the Indian city of Mumbai. The attack was not complex because of the weapons used or its size, but in the apparent training, multiple methods of approaching the city and excellent operational security and discipline in the final phases of the operation, when the last remaining attackers held out in the Taj Mahal hotel for several days. The operational goal of the attack clearly was to cause as many casualties as possible, particularly among Jews and well-to-do guests of five-star hotels. But attacks on various other targets, from railroad stations to hospitals, indicate that the more general purpose was to spread terror in a major Indian city.
While it is not clear precisely who carried out the Mumbai attack, two separate units apparently were involved. One group, possibly consisting of Indian Muslims, was established in Mumbai ahead of the attacks. The second group appears to have just arrived. It traveled via ship from Karachi, Pakistan, later hijacked a small Indian vessel to get past Indian coastal patrols, and ultimately landed near Mumbai.
