WASHINGTON - The United States on Monday stepped back to ease tensions with Pakistan resulting from Secretary of State Hillary's Clinton's stern warnings, saying it is pleased with the help Islamabad is extending in the ongoing investigation into May 1 Times Square botched car bombing attempy. "We are pleased with the level of cooperation that we've gotten from the Pakistani government. We have a partnership with them. And we have seen them for the first time, in the last year, take on the threat that existed within their country, that they had not addressed in quite some time," White House Press Secretary Robert Gibbs said. In an interview with CBS television, Mrs. Clinton had warned Pakistan that it would face "very severe consequences" if any terror plot like the failed Times Square bombing was traced to that country. "We've made it very clear that if, heaven forbid, an attack like this that we can trace back to Pakistan were to have been successful, there would be very severe consequences," she had said. And she followed up that warning by claiming hat some elements in the Pakistani government know about the whereabouts of Al-Qaeda and Taliban leaders, including Osdama bi Laden-- something the U.S. military and intelligence agencies have not been able to determine with all their sophisticated equipment. The White House spokesman would not go into specifics about the investigation involving suspect Faisal Shahzad, a US citizen of Pakistani descent, but said that the two countries have good relations. "I would characterize our relationship as good. I would characterize the one of the things that has happened, over the course of the past year, is a far greater cooperation between the two governments. And pleased with that continued cooperation now," Gibbs stated at the daily briefing. Meanwhile, General Stanley McChrystal, the commander of USforces in Afghanistan, on Monday called for understanding Pakistan's "major" anti-Taliban effort and denied reports that he had asked Pakistani army chief to do more in fighting the militants. "There was an unfortunate news story that came out that was completely inaccurate. It represented that I had expressed to General Kayani US policy on doing more. That just did not happen," McChrystal told a White House briefing. "In our one-on-one meeting that did not occur. And I 've made it clear to (Pakistani army chief) Gen Kayani that I did not not represent it that way," he added when suggested that Pakistan was not focusing enough on the Afghan Taliban that may have taken refuge in North Waziristan tribal area. The top US commander in Afghanistan was speaking in the backdrop of reports that claimed that the US is pressuring Islamabad to extend its anti-militancy operations to North Waziristan in the wake of the Times Square bombing attempt, which is being linked to the Pakistani Taliban. Gen McChrystal drew attention to Pentagon's assurance to Pakistan that the U.S. military is not pressuring the Pakistani army to increase its operations against the Taliban there.
