I can assure you, nobody calls the whole nation of Pakistan as liars. People can see the difference between the individual qualities and national policies.
I can take this discussion further, but it belongs in another topic IMO.
Suffice to say here, that the whole nation is paying the price for its leaders' follies, and the poison is seeping downwards into all layers of its society. Unless halted, the whole nation will eventually be poisoned.
That is also part of the reason why the OBL issues raises so much angst for it showed the reality in a very dramatic way. Pakistan can either deny it, or accept it and rectify what led to the whole saga.
That is a choice for Pakistan, both people and government, to make.
I hope they choose wisely.
