ISLAMABAD, Pakistan — Despite mounting pressure from the United States since the American raid that killed Osama bin Laden, Pakistan’s army chief, Gen. Ashfaq Parvez Kayani, seems unlikely to respond to American demands to root out other militant leaders, according to people who have met with him in the last 10 days.

While the general does not want to abandon the alliance completely, he is more likely to pursue a strategy of decreasing Pakistan’s reliance on the United States, and continuing to offer just enough cooperation to keep the billions of dollars in American aid flowing, said a confidant of the general who has spoken with him recently.

Such a response is certain to test American officials, who are more mistrustful of Pakistan than ever.

Emboldened by the May 2 raid that killed Bin Laden in Pakistan, American officials say they now have greater leverage to force Pakistani cooperation in hunting down Taliban and Qaeda leaders so the United States can end the war in Afghanistan.
