Khawaja Asif's warning came amidst reports that the army has decided to continue with targeted air strikes on Taliban bases in case of an attack on a military installation.
Asif said the government was seeking the army's advice over the future course of action in the dialogue process.
Speaking to Geo News, Asif said the next phase of dialogue will be based on intelligence information provided by the army.
"The army will provide information on what options are available to the government," he said.
The minister made it clear that the duration of the dialogue process cannot be indefinite and if there is no progress, the government will have to use the option of force.
"If the ceasefire is violated, the government will be left with no other option but to launch an operation," he was quoted as saying.
On Monday, gunmen had attacked a courtroom in Islamabad, killing 11 people in the heart of the heavily guarded capital.
But the Pakistani Taliban denied any role in the attack and a splinter group claimed responsibility.
Dawn News reported that a meeting of the corps commanders, chaired by army chief Gen Raheel Sharif today decided that air strikes on militant hideouts would continue in the event of future attacks on military installations.
Asif stressed that the entire government machinery including the army is available for talks.
"It is the prime minister's discretion to include anyone in the new committee," he said.
The four-member government committee, constituted to hold peace talks with the Taliban, will be replaced soon.
According to reports, a new committee would be formed consisting of ISI officials, representatives of the federal cabinet, the Khyber Pakhtunkhwa government and the governor to hold direct talks with the Taliban.
