NEW YORK - A leading U.S. newspaper Saturday called on India to limit its demands on Pakistan as it investigates last week's attacks in Mumbai, and demanded that New Delhi clarify its involvement in Afghanistan. In an editorial, The New York Times also asked India to share intelligence with Pakistan, while stressing that the Pakistani government cooperate with the Indian investigation. "Instead of boxing (President Asif Ali) Zardari in, it (India) should ask his government to arrest only people who are directly linked to the Mumbai attacks, not other incidents," the newspaper said in a lead editorial, its second on the situation arising from Mumbai attacks. "At a minimum, his government must be ready to arrest and try anyone involved in the attacks, and mete out long jail terms if they are convicted. Islamabad must finally shut down all the Lashkar training camps and recruitment activity. "We also are waiting for a forceful public repudiation of the militant groups from the Army chief of staff, Gen. Ashfaq Parvez Kayani, and his personal pledge that all ties between Pakistan's military and the extremists will be severed. His silence is deafening." The Times said, "For any lasting peace, India and Pakistan must settle their dispute over Kashmir, the biggest flashpoint. India's growing investment and intelligence network in Afghanistan also is feeding Islamabad's insecurity and sense of encirclement. India must be transparent about its involvement in Afghanistan. "If the two countries are going to inch back from the brink, they will need strong support from the United States, China and others powers. These countries also must develop a strategy to strengthen Pakistan's fragile civilian government and stop the country from becoming even more ungovernable. "That does not mean impunity for anyone involved in the Mumbai attacks. It means that the leaders of Pakistan's military and intelligence services must finally realize that the extremists pose a clear and present threat to their own country's survival".
