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. The Secretary of State said Pakistan's attitude toward fighting Islamic terrorists has changed remarkably. Her comments came in the backdrop of failed Times Square bombing plot last week in which a explosives-laden car was planted by Faisal Shahzad. A naturalised American citizen born in Pakistan, Shahzad admitted of being trained by terrorists in Waziristan.
