A premier US think-tank has cautioned India against "more spectacular attacks" by terrorists, saying such incidents could also create "bigger problems" for Pakistan than it could handle.Warning that Kashmiri militant outfits were being increasingly drawn into the global jihadist camp, the Srategic Foresight Inc., known as Stratfor, says "if Pakistan is unable to reassert its control over the Kashmiris before such an attack occurs, it could find that the LeT (Lashkar-e-Taiba) has created a bigger problem than Islamabad can handle"."A major attack on India with thousands dead will find New Delhi in a much less forgiving mood", the Austin-based think-tank said.In a recent report, it said Pakistan, "still has a firm grip on the larger, more mainstream Islamist groups operating within its borders and in Pakistan-controlled Kashmir, such as Hizbul Mujahedeen and the United Jihad Council."But groups like LeT, Al Badr and Jaish-e-Mohammad are much more autonomous. Though Pakistan still maintains some tacit contact with and control over them, these groups, for the most part, operate independently of Islamabad since they were banned" in the fallout of the 2001 attack on Parliament, the Stratfor report said.
