Islamabad: US President Donald Trump’s strategy for the nation’s longest-running war in Afghanistan will meet the same fate as the plans of his predecessors, according to Pakistan’s Prime Minister, Shahid Khaqan Abbasi. Failure.

“From day one we have been saying very clearly the military strategy in Afghanistan has not worked and it will not work,” Abbasi, who took over as premier three weeks ago, said in an interview on Saturday night in Karachi. There has to be a “political settlement”, he added. “That’s the bottom-line.” Abbasi said while his government supports the fight against terrorists it won’t let the war in neighbouring Afghanistan — the countries share a 2,500-kilometre border — spill into Pakistan.

The stance of Abassi’s administration may complicate Trump’s plan for the region after he pledged more US troops for Afghanistan and called on Pakistan to stop providing a safe haven for terrorists.

Failure by Trump to resolve the Afghan war risks even greater financial and human cost for the US, could leave it bogged down further in the conflict, and may become a further sore point for ties with China and Pakistan, with Trump already chiding Beijing for not doing enough to stop the turmoil. The war has cost the US about $714 billion and several thousand lives.

Afghanistan’s government is slowly losing its hold over the country with the Taliban now controlling about 40 per cent of the country, which US officials say couldn’t have been possible without help from Pakistan’s military. That’s a charge the Asian nation disputes.

The US in previous offensives in Afghanistan used drones to attack alleged terrorists in Pakistan. Nato troops have also used Pakistani ports and roads to move equipment into landlocked Afghanistan.

“We do not intend to allow anybody to fight Afghanistan’s battle on Pakistan’s soil,” Abbasi said during the interview at the former home of the nation’s founder, Mohammad Ali Jinnah, while he was on a visit to the nation’s commercial capital. “Whatever has to happen in Afghanistan should be happening in Afghanistan,” he said, adding Pakistan doesn’t harbour terrorists.

Abbasi was picked by the ruling party as prime minister this month after the nation’s top court disqualified predecessor Nawaz Sharif in July.

Support and investment from China will help Pakistan defy the US China, which is seeking to build its economic and strategic clout in South Asia, has more than $50 billion in planned infrastructure projects in Pakistan.

Pakistan’s military has been conducting its own offensive against terrorists with the latest operation in the Khyber tribal region starting last month after Daesh’s presence increased across the border in Afghanistan. The Pakistani army earlier said it had cleared North Waziristan on the Afghanistan border, a region the US has called an “epicentre” of terrorism.

More than 60,000 people have been killed while Pakistan’s economy has suffered a loss of about $120 billion from waging war at home against terrorists, according to the finance ministry. The nation also became one of the largest hosts to refugees globally after Afghans started crossing the border to flee the war after the September 11, 2001 attacks on the US.

Pakistan has started returning refugees and plans to fence its border with Afghanistan to prevent the cross-border movement of militants.

Abbasi said Pakistan is willing to work with all countries including India, from whom Trump sought help to develop Afghanistan’s economy, to achieve regional stability. Still, he added the Afghan government should be “owning” the issue and dealing with the Taliban.

“If they require our support, our support is available,” he said. “Our support is unconditional as far as terrorism is concerned.”
