US Pakistan relations over US general's claim:

Excerpts:
Pakistan's army chief General Ashfaq Pervez Kayani chaired a special meeting of his top commanders on Sunday amid an escalating war of words with the United States. Ties between the two allies have plunged to a new low following U.S. allegations the Pakistani spy agency is encouraging and aiding deadly militant attacks on U.S.- led international forces in Afghanistan.
The corps commanders gathered in the General Headquarters in Rawalpindi against the backdrop of growing American allegations that the Pakistan army’s spy agency, the ISI, is assisting the militant Haqqani network to launch attacks on U.S. targets in neighboring Afghanistan.
The outgoing chairman of the U.S. Joint Chiefs Staff, Admiral Mike Mullen, told a Senate hearing last week that the Haqqani network acts as a “veritable arm” of the Pakistani spy agency, and its fighters planned and conducted this month’s assault on the U.S. embassy in Kabul as well as NATO bases in Afghanistan.
Pakistan’s civilian and military leaders have rejected the accusations as baseless and said they are detrimental for regional peace efforts.
Speaking to reporters in Islamabad Sunday, Interior Minister Rehman Malik insisted that the Haqqani network is not operating from Pakistan. He alleged the network was produced and trained by the American CIA with support from Pakistan to fight the Soviet occupation of Afghanistan in the 1980s.
“They are operating in Afghanistan. If anybody has got any evidence to this effect (that they are in Pakistan) please bring it to us," said Malik. "We are cooperating with U.S. We will cooperate with every country of the world who is fighting against terrorism.“
The minister said he has ordered tighter border controls for checking up to 50,000 people moving between Pakistan and Afghanistan every day.
Pakistan "will cooperate with every country of the world who is fighting against terrorism" yet they do nothing about the terrorism within their own country.
And of those 50,000 that pass through every day - there are no Pakistani terrorists, just Afghani terrorist. 
I'm sure a request for "proof" that the statement by the US general is true, is forthcoming.
