A top U.S. official has said that the Trump administration will not shy away from taking tougher steps against Pakistan.

“This administration will not shy away from some tougher steps if they have to, to try to convince Pakistani leaders that it's in their own interest to crack down on these groups,” the official said.

Speaking on the condition of anonymity, the official said the Trump administration thinks that not having a timeline for troop withdrawal from Afghanistan will prevent Pakistan from the hedging it has previously done.

“We think their continued support to some of these groups is because there's so much uncertainty about the US commitment to the region,” the official said regarding the new US strategy for the region.

It came after Trump reversed United States’ policy on South Asia, warning Pakistan of consequences if it continued to provide safe havens to terrorists.

“We have been paying Pakistan billions and billions of dollars at the same time they are housing the very terrorists that we are fighting,” Trump said. “It is time for Pakistan to demonstrate its commitment to civilization, order, and to peace.”

He also said that US troops would remain in Afghanistan, and urged India to play a larger role in the country to promote stability.
