Ms Nauert said that despite high-level talks between Washington and Pakistan's government, "the Taliban and Haqqani network continue to find sanctuary inside Pakistan as they plot to destabilise Afghanistan and attack United States and allied personnel".
Pakistan denounced Washington's decision to suspend hundreds of millions of dollars in security assistance as "counterproductive" Friday, in a carefully-worded response to the frustrated Trump administration's public rebuke over militant safe havens.
The US, under the Donald Trump government, has announced a suspension of its security assistance to Pakistan for its failure to take decisive steps against terrorists targeting US personnel in Afghanistan.
The decision to cut funding comes just several days after President Donald Trump tweeted his disappointment with Pakistan, claiming that the US got nothing but "lies and deceit" for the $33 billion in aid the USA gave Pakistan between 2002 and 2018.
Relations between Pakistan and the US long have been strained, and tensions have only grown since the summer, when the Trump administration announced its policy on Afghanistan and South Asia. She said Trump is willing "to go to great lengths to stop all funding from Pakistan as they continue to harbor and support terrorism". He suggests that it is the time for Washington to end Pakistan's double games.
"Pakistan is one of the most duplicitous governments I've had any involvement with", Senator Bob Corker, Republican chairman of the Senate Foreign Relations Committee, told reporters. He reiterated longstanding allegations that Pakistan gives "safe haven to the terrorists we hunt in Afghanistan". Nicholson said the US military would like to see the Pakistanis eliminate the Taliban's sanctuary across the Afghan border.
On Monday, Trump said the USA had "foolishly" given Pakistan more than $33 billion in aid in the last 15 years and had gotten nothing in return but "lies & deceit".
Sherry Rehman said that Pakistan knows well that how to deal its matters.
It said that Pakistan believed that its cooperation with USA in fighting terrorism directly served USA national security interests as well as the larger interests of the global community. The $33 billion Trump referred to represents all US military and economic aid to Pakistan since 2002.
"However, Congress and the public are concerned that Pakistan is not producing a measurable result to correlate with US investment", the report said.
"The timing and nature of the Trump administration's decision are worrisome".
The military aid, known as foreign military financing, "promotes the development of Pakistan's long-term [counter-insurgency/counter-terrorism] capabilities and improves Pakistan's ability to participate in maritime security operations and counter-maritime piracy", according to the State Department.
But he said it could be a backup plan in response to the Indo-Pacific strategy of the USA and its allies.
Currently, the USA and North Atlantic Treaty Organisation depend on Pakistan for logistical support for their operations in Afghanistan, a key part of fighting terrorism.
In contrast to recent visits by U.S. Secretary of State Rex Tillerson and Defense Secretary Jim Mattis who spoke of "engagement and trust-building during their visits here. now President Trump and Vice President Pence are talking of threats, insults and 'putting Pakistan on notice, '" Dastagir said.
Hours before the tweet, a US Special Forces soldier had been killed in Afghanistan's Nangarhar province, which borders Pakistan, and four were injured in a terrorist attack.
