The military also decided not to put forth a formal public response. In what could be viewed as a pre-emptive move, Major Gen Asif Ghafoor, the military spokesman, had said in a press briefing earlier on Monday that no terror group was operating inside Pakistan.

Sehar Kamran, an opposition senator who leads an Islamabad-based think tank, said Mr. Trump’s plan appeared to be “more of the same, under much more colorful language and contradictory bluster.”

“The shift from a timeline-oriented approach to a condition-based one, I think, is only the vocalization of a longstanding practice,” she said, adding. “What is concerning for Pakistan, however, is the contradiction within his statement that expresses both an acknowledgment of the country’s sacrifices while simultaneously downplaying them by continuing accusations of ‘sheltering terrorists,’ and doing not enough with billions and billions paid by America.”

Ms. Kamran said that pushing India to play a stronger role inside Afghanistan would isolate Washington’s friends in Islamabad “without realizing, understanding or perhaps deliberately underestimating the impact of increasing Indian presence on Pakistan’s western border.”

“An unnecessary flexing of military muscles and the deployment of additional troops at this time will only undo much that has been achieved over many years diplomatically, and serve to further antagonize regional countries like Pakistan, China and Russia,” she said.

Analysts said Pakistan’s dependence on American aid had declined in recent years — partly as China flexes its military might in South Asia — giving policy makers in Islamabad more room to maneuver.

“Pakistan is prepared to absorb the impact of a more assertive U.S. policy toward the country,” said Arif Rafiq, a nonresident fellow at the Middle East Institute in Washington. “It’s the most economically stable that it’s been in a decade, thanks in part to massive Chinese investment, and it has managed to secure much of its border regions despite the withdrawal of most U.S. combat forces.”
