WASHINGTON: A key US lawmaker has introduced a legislation in the House of Representatives to stop American aid to Pakistan, saying the killing of Al-Qaeda chief Osama bin Laden in Abbottabad has made it clear that Islamabad concealed, protected and enabled him for many years. We can no longer afford this foolishness, Congressman Dana Rohrabacher said after introducing the 'Defund United States Assistance to Pakistan Act of 2011 in the House of Representative. The time has come for us to stop subsidizing those who actively oppose us. Pakistan has shown itself not to be Americas ally, he said. Rohrabacher is a senior member of the House Committee on Foreign Affairs and Chairman of the Subcommittee on Oversight and Investigations. The bill outlines several accounts of Pakistans duplicitous behaviour toward the US including recent reports of Pakistani leadership lobbying Afghan President Hamid Karzai to move away from 'imperial America and to embrace Communist China, said a statement issued by the Congressman. During last weeks raid in Abbottabad, a specially configured stealth US Special Forces helicopter crashed and even though US soldiers attempted to destroy it, the tail was left intact and recovered by the Pakistanis. Rohrabacher demanded immediate return of the debris for fear of American military secrets being compromised. If this is not done immediately, it is probable, given Pakistans history, that our technology has already found its way into the hands of the Chinese military that is buying, building, and stealing the necessary military technology to challenge the United States, said Rohrabacher.
