Despite receiving billions of Dollars of American tax-payer's money as aid to sustain its impoverished, terrorism infested country, the Islamic Republic of pakistan's Army continues to harbor & actively support & direct those terrorists who plot the murder and killing of American troops stationed in Afghanistan, fighting the pakistan-backed Taliban terrorists.
In fact, in a perverse twist of irony, this very money being poured by USA into pakistan enables them to continue killing American soldiers in Afghanistan.
American tax-payers are financing pakistan to kill US soldiers - possibly their own, brothers, sisters, husbands, wives, daughters, sons - blood of US soldiers on American tax-payer's hands.
