Since coming to power in September, Ghani has sought to jumpstart long-stalled negotiations with the Taliban for a peace agreement 13 years after they were toppled in a US-led invasion.
Ghani has courted Washington to slow the drawdown of US troops and longtime nemesis Pakistan, which has historically backed the Taliban, in what observers say is a calculated gambit to pressure the insurgents to the negotiating table.
Former Afghan president Hamid Karzai, well known for his anti-US and anti-Pakistan tirades, and others have warned strongly against Afghanistan's tilt towards Islamabad -- often accused of playing a "double game" and covertly nurturing the Taliban.
Ghani, an American-educated former World Bank official who uses a more measured tone, has offered unprecedented concessions to Pakistan including cooperation on military and intelligence matters.
He sent Afghan cadets to study at the Pakistani military academy and reportedly suspended Karzai's long-standing order for heavy arms from India, whose influence in Afghanistan has long made Pakistan wary.
"The second constituency worries about the cost of rapprochement with Pakistan. Would Afghanistan give up its democratic constitutional process to create space for the Taliban? Would it mean giving up its independent foreign policy? Would Afghanistan become Pakistan's (captive) market and passage to Central Asia?"
"Ghani has to address both constituencies," Moradian told AFP.
Ghani has cited a massacre by Pakistan's Taliban at a school in the Pakistani city of Peshawar in December that killed 153 people, mostly children, as helping to bring the two governments closer together.
"Terrorists neither require passports nor recognise nationalities," Ghani said during his landmark US visit last week.
"I'm hopeful that we will have sufficient wisdom not to sink but to swim together," he added.
