In one of the harshest actions in years between the troubled allies, Washington moved to block the military aid at the end of a contentious week that began with Trump bashing Islamabad for years of "lies & deceit" as well as for harbouring terrorists.
The US State Department officials said they were holding back the aid as an incentive for Islamabad to take "decisive action" to rid its lands of terrorist safe havens. It also placed Pakistan on a watch list of countries failing to protect religious freedom.
"Working towards enduring peace requires mutual respect and trust along with patience and persistence," Pakistan's Foreign Ministry said in a statement. "Arbitrary deadlines, unilateral pronouncements and shifting goal posts were counterproductive in addressing common threats."
The Ministry defended Islamabad's stance on terrorism, saying that "it has fought the war against terrorism largely from its own resources which has cost over $120 billion in 15 years.
"We are determined to continue to do all it takes to secure the lives of our citizens and broader stability in the region."
In an interview on Thursday with the Geo News channel, Foreign Minister Khawaja Asif said that the US was now neither a friend nor ally, but "a friend who always betrays". He also accused Trump of "speaking the language of India".
Pakistan's opposition, meanwhile, called for concrete actions to retaliate.
Pakistan Tehreek-e-Insaf (PTI) chief Imran Khan said Pakistan should "delink" itself from the US after its humiliation "by an ungrateful Donald Trump".
Addressing a fiery press conference outside his residence in Islamabad, Khan called the Pakistan government to expel some US diplomatic personnel and cut off supply routes for the US-led coalition forces from the port city of Karachi to landlocked Afghanistan, as well as close its airspace to US forces.
The political elite of Pakistan were responsible for the threats and strained relations between the two countries, Khan said, referring to the Pakistan Muslim League-Nawaz (PML-N) government.
The US has given Pakistan more than $20 billion in reimbursements and military assistance since 2002, but that aid has diminished over the years, to the point that Pakistani officials have insisted its suspension will have minimal impact, the New York Times reported.
"The suspension is arguably more significant as a signal of Washington's discontent than as an act of financial deprivation," said Joshua T. White, an Asia analyst who was director of South Asian affairs at the National Security Council during the Obama years.
"The Trump administration has likely sketched out an escalation strategy, and would be wise to pause after Thursday's announcement to give Pakistan the opportunity to quietly address US concerns."
