The US seems to have just woken up to the fact that its ally Pakistan lies.

Apparently, the detention of CIA informants by Pakistan's top spy agency has sparked palpable outrage in US Congress at an ally that receives more than two billion dollars a year in American aid.  

ISI agents have arrested some Pakistanis in recent weeks for allegedly helping the CIA gather intelligence before the May 2 US raid that killed al Qaeda leader Osama bin Laden.  

"How long do we support governments that lie to us? When do we say, ''Enough is enough''? They arrested people who helped us get him [bin Laden]," ABC News quoted Senator Patrick Leahy, as asking Defense Secretary Robert Gates at a Senate Appropriations Committee hearing.  

Gates prompted laughter with his response: "First of all, I would say, based on 27 years in CIA and four-and-a-half years in this job, most governments lie to each other. That's the way business gets done."
