Most countries (including Pakistan) require a minimum of six months validity on your passport. Be aware that this may also apply to any countries you're transiting through (I'm assuming there's no direct flight from the US).

According to the Pakistan page at travel.state.gov,
PASSPORT VALIDITY:
Six months beyond the date of arrival
There don't appear to be any exceptions to this. However, I couldn't find a page on a Pakistan government site that says anything about passport requirements.
