United States troop pullout will leave behind an uncertain Afghanistan

The Biden administration's surprise announcement of an unconditional troop withdrawal from Afghanistan by September 11 appears to strip the Taliban and the Afghan government of considerable leverage and could ramp up pressure on them to reach a peace deal.

The Taliban and Afghan government can no longer hold the US hostage - the Taliban with escalating violence and the Afghan president with dragging his feet on a power-sharing deal with the insurgents that doesn't include him as president - because Washington made it clear that US troops are leaving, no matter what.

Still, there are growing fears that Afghanistan will collapse into worsening chaos, brutal civil war, or even a takeover by the Taliban once the Americans are gone - opening a new chapter in the constant war that has lasted for decades.

Already, violence and seemingly random attacks on civilians have surged since the Trump administration reached a deal with the Taliban in February 2020 that had committed Washington to withdraw by May 1. More than 1,700 civilians were killed or wounded in attacks the first three months of this year, up 23 per cent from the same period last year, according to the UN Assistance Mission in Afghanistan.

On Wednesday, the Biden administration set a new timetable. It said it would begin pulling out its remaining 3,500 troops on May 1 and complete the pullout at the latest by September 11 - the 20th anniversary of the al-Qaida terror attack on the US that had triggered the US-led invasion of Afghanistan. NATO announced it would follow the same timetable for withdrawing nearly 10,000 troops.

In leaving, Washington has calculated that it can manage its chief security interest - ensuring Afghanistan doesn't become a base for terror attacks on the United States - from a distance.

Still, it is hoping to leave a country with a chance at peace. The US is pressing the Taliban and the Afghan government to reach a peace agreement during an April 24-May 4 conference in Turkey.

At the moment, it's not even sure the Taliban will attend.

In response to the new withdrawal timeline, the Taliban said they won't attend any conference on Afghanistan's future while foreign forces are still in the country. A spokesman, Zabihullah Mujahed, said that if the original May 1 deadline is not met, problems will be compounded." Still, he did not explicitly threaten a resumption of Taliban attacks on US troops.

US Secretary of State Antony Blinken upped the pressure with a phone call Wednesday to Pakistan's powerful Army Chief of Staff Javed Qamar Bajwa, presumably seeking help in getting the Taliban to the Turkey conference.

With their leadership headquartered in Pakistan, the Taliban ignore Islamabad at their own peril. Until now Pakistan has been key to getting the insurgent militia to earlier rounds of talks.

The Pakistani army said afterwards that Pakistan was behind an Afghan-owned and Afghan-led peace process, a seeming nod to the upcoming Turkey conference. It also said the two discussed further enhanced relations between their countries - perhaps a sign Blinken tied future US-Pakistani relations on Islamabad's help.

The Taliban control around half of Afghanistan. But they also have much to lose if they walk away from the peace process, particularly a chance at international recognition. The group has been courting world powers since 2013 when they set up their political office in the Qatari capital Doha.

The US has warned that the Taliban won't get that recognition if they are not part of a new government. The Turkey conference, jointly convened by the United Nations, lends international support to that warning.

The bet is that the Taliban won't want to rule as a pariah, as they did from 1996 until their overthrow by the US-led coalition in 2001. They had no money to feed their people, unemployment was rampant and drought and poverty devastated farmers. Their only source of income in the final years was from al-Qaida and its wealthy Saudi leader at the time, Osama bin Laden.

If the Taliban wants recognition, if they want international support ... that can't happen if they press war further, Blinken said on Meet The Press on Sunday. We'll see how the parties calculate their interest.

Torek Farhadi, a former Afghan government adviser, said he doesn't expect the insurgents to attend in Turkey.

Instead, he said, they are likely to negotiate with local leaders around Afghanistan and wait for the Americans to leave, further weakening and isolating President Ashraf Ghani. The Taliban have refused to even sit across the table from him.

Responding to the US strategy shift, Ghani pledged to pursue peace, without elaborating. He tweeted late Wednesday that he had spoken with President Biden and we will work with our US partners to ensure a smooth transition.

Previously, Ghani had floated an alternative peace plan that calls for him to head an interim government until fresh elections can be held. Rejected by the Taliban, it's seen by his political opponents as an attempt to cling to power.

Ghani's government has been denounced for runaway corruption and divisive politics. He has embraced warlords he once shunned, like Uzbek powerhouse Rashid Dostum, accused of war crimes.
