Such a warning, ahead of the Chicago summit later this month which is expected to take crucial discussions related to Afghanistan, came from none other than Senator John Kerry, Chairman of the powerful Senate Foreign Relations Committee and architect of the Kerry-Lugar-Berman Bill that allotted USD 7.5 billion to Pakistan for five years.
"I personally think it is simply unacceptable to have a zone of immunity for acts of war against armed forces and against the collective community that has tried to accomplish what it has tried to accomplish," Kerry said in his remarks at a Congressional hearing convened by him on the upcoming NATO Summit in Chicago.
"That means Pakistan has to become more assertive and more cooperative, and we may have to resort to other kinds of self-help, depending on what they decide to do," said Kerry, who in the Obama Administration is considered to be the best friend of Pakistan.
Several times in the past three years, Kerry had flown to Pakistan to troubleshoot when all other means have failed be it the Raymond Davis Case or the helicopter that got damaged in the Osama bin Laden raid at Abbottabad a year ago.
Such remarks coming from Kerry are reflective of the changing mood in the United States particularly at a time when the two countries are holding crucial negotiations on the reopening of the ground lines of communications and other related issues between them.
