ISLAMABAD (Agencies) Washingtons troubled relationship with Islamabad has triggered plenty of heartburn, but rarely sidesplitting laughter. That changed Friday when Secretary of State Hillary Rodham Clinton erupted in amusement during a town hall meeting in the capital when a participant described the US as Pakistans impossible to please mother-in-law. We all know that the whole of Pakistan is facing the brunt of whatever is happening and trying to cooperate with the US, and somehow the US is like a mother-in-law which is just not satisfied with us, said a woman who identified herself as Shamama and elicited a round of applause from the crowd. We are trying to please you, and every time you come and visit us you have a new idea and tell us, 'You are not doing enough and need to work harder, said Shamama, who works for a womens group in Khyber Pakhtunkhwa. Laughing at length, Clinton said she could personally relate to the womans perspective because she too was a mother-in-law. The secretary of states daughter, Chelsea, married an investment banker this summer in New York. I think thats a great analogy I have never heard before, said Clinton. Now that I am a mother-in-law, I totally understand what youre saying and hope to do better privately and publicly. I personally believe this relationship is critical, important to us both, and therefore we cannot give it up, said Clinton. Once a mother-in-law always a mother-in-law, but perhaps mothers-in-law can learn new ways also. The US and Pakistan have long had a troubled relationship that got even worse this year following the arrest of a CIA contractor, the covert raid that killed Osama bin Laden in a Pakistani garrison town and, most recently, allegations that Pakistans spy agency has supported militants attacking American targets in Afghanistan. Pakistan has denied the claim. The U.S. has given Pakistan billions of dollars in military and civilian aid in an attempt to elicit greater cooperation on the Afghan war, but has come away frustrated. Pakistani officials and ordinary citizens have also soured on the relationship, perceiving the U.S. as only interested in buying the countrys anti-terror cooperation, rather than investing in a long-term partnership.
