As STRATFOR has argued, inaction in the face of the Nov. 26 Mumbai attack is probably not an option for the Indian government. However, India also is not interested in a full-scale war with Pakistan or the collapse of the Pakistani government. Islamabad has given indications that, despite institutional links, those responsible for the Nov. 26 attacks were not acting under the direction of the upper echelons of the Pakistani government. New Delhi hopes to pressure Islamabad to do what it so far has been unable or unwilling to do — namely, rein in rogue elements of the Inter-Services Intelligence (ISI) and the militant groups operating in Pakistan. To do so, India must demonstrate its resolve — including its military resolve — to show Pakistan that New Delhi will take increasingly overt measures to crush these groups if Islamabad does not establish control over its own government and territory.
