India will be compelled to again break off recently resumed talks with Pakistan if investigators determine that Pakistan-based Lashkar-e-Tayyiba (LeT) played a crucial role in the planning and implementation of yesterdays Mumbai attacks, a former CIA officer and Senior Research Fellow at Washingtons Heritage Foundation has said. Three bomb blasts ripped through crowded Mumbai streets on Wednesday evening, killing at least 21 people and wounding over 130 others, in a gruesome echo of the terrorist attacks that paralyzed the city three years ago. It is too early to determine who is responsible for the attacks, but Indian authorities are pointing to the possibility of the Indian Mujahideen (IM), a homegrown outfit with links to the Pakistan-based Lashkar-e-Tayyiba (LeT), Lisa Curtis said. The strength of the links of these bombings to the LeT will determine how India responds. If investigators determine that LeT members played a crucial role in the planning and implementation of todays attacks, the Indian leadership will be compelled to again break off recently resumed talks with Islamabad. If, on the other hand, investigations show that the IM carried out these bombings largely on its own, there will be less pressure on Indian leaders to immediately withdraw from the IndoPakistani dialogue, she added. Curtis further said that the United States should do everything they can to counsel calm in both Islamabad and New Delhi. They should also make clear to Pakistani officials that, whether or not the attack originated in Pakistan, now would be an opportune time to move ahead with the prosecutions of the LeT members involved in the 2008 attacks to show their good faith and help keep dialogue with India on track, she said.
