US Senator Gary Ackerman has said Pakistans 'self-centred interest is in contradiction with the American interest, reported a private TV channel on Thursday. Pakistan military is not our ally. They are not supporting the US. Despite military aid, Pakistan did not change its policies, the US congressman said. He added that 75 per cent of Pakistanis do not consider the US cause of their problems. Pakistan backs extremists. America must understand that Pakistans self-centred interest is in direct clash with that of the American interest. The US must open her eyes now, he added.
