Explain about this article about the US relationship with Pakistan?
This is in no way surprising. The US relationship with Pakistan is very tense and will remain so for the foreseeable future.
The US and Pakistan need each other, but they have very little in common to serve as a basis for a solid relationship. Pakistan is, of course, a Muslim nation and many Muslims are very suspicious of US efforts in the "war on terror." A large number of Pakistanis are Pashtun at a time when the US war in Afghanistan is seen as a conflict against the Pashtun people. The US has a good relationship with India, which is Pakistan's major enemy.
Because of all these things, Pakistan will have a very hard time trusting the US and the US relationship with Pakistan will remain tense.
