The US has warned Pakistan it will face very severe consequences if a terror plot like the botched Times Square bombing is traced to that country. Secretary of State Hillary Clinton has said, the US expects more cooperation in fighting terror from the Pakistan government and warned there could be repercussion if any future successful terror attacks in America are linked to Pakistan. In an interview to CBS Television, She acknowledged that Pakistan had become far more helpful in battling terrorists during the past year, but cooperation could be improved. Earlier the Obama Administration asked Pakistan to expand its counter-terrorism operations from the Afghan border to Punjab, where most of anti-India terror groups like LeT are based. Assistant Secretary of State for South and Central Asia, Robert Blake said, the principal problem that prevents the two countries from holding peace talks is that of terrorism.
