Georgetown Prof. C. Christine Fair has an outline of the Lashkar-e-Taiba (LeT) in India Today. She also has a stark warning:
While Indians are likely correct to anticipate that the next attack on India may well come from the LeT; I encourage Indians to also remember the Jaish-e-Mohammad which launched the attack on India's parliament in December 2000. JeM had been dormant for years in part because their cadres had defected to the Pakistani Taliban. In recent years, the Pakistan army and ISI have resuscitated JeM in hopes of luring some of the previous cadres back into the fold with the lure of killing Indians. JeM, it should be recalled, conducted its first attack-a suicide bombing in 2000-in Kashmir. JeM, unlike LeT, has long had ties to al Qaeda and the Afghan Taliban, once the world leaders in murderous brutality, and JeM's operatives have been working with the Pakistani Taliban whose attacks have been nearly as savage as that of IS. Indians would be wise to keep on eye on JeM in addition to LeT. The Pakistan army and the ISI needs both of these groups if its twin goals of pacifying Pakistan and setting India on fire are to be advanced.
