Millions of Afghans are anticipating that America’s longest war fought in their country will end on Saturday as US and Taliban negotiators are expected to sign a deal to allow a US troop reduction and a permanent ceasefire.

If the US-Taliban agreement gets signed, then Afghanistan, which has been at war since American bombings began in response to the Sept.11, 2001 attacks, will witness the potential end of violence that has claimed tens of thousands of lives.

“Peace is extremely simple and my country deserves it. Today is the day when maybe we will see a positive change,” said Javed Hassan, 38, a school teacher living on the outskirts of the capital, Kabul.

Hassan’s children were killed in a bomb blast carried out by the Taliban in 2018. Since then, he has been writing letters to world leaders urging them to end the Afghan war that has dominated the landscape of the land-locked country.

Saturday’s deal could be the first step towards resetting Afghanistan’s future as US Secretary of State Mike Pompeo is set to witness the signing of the agreement on a withdrawal of American troops and prepare the ground for a political settlement between the warring sides.

In the Qatari capital of Doha, America’s top diplomat will stand with political leaders of the Taliban, Afghanistan’s former rulers who sheltered Osama bin Laden and his militant network until 2001 as he plotted and conducted the 9/11 attacks.

A statement from US President Donald Trump on Friday said Pompeo would be present for the signing of the deal that will pave way for US troop numbers to drop to 8,600 from about 13,000 in the weeks following the deal.

Further reductions of western forces will hinge on the Taliban adhering to a “reduction in violence” pledge, a condition that will be assessed by the United States.

But prospects for war-torn Afghanistan’s future are uncertain. The agreement sets the stage for peace talks involving Afghan factions, which are likely to be complicated.

Under the deal, the Taliban wants 5,000 fighter to be released from Afghan-run jails, but it’s not clear whether the Afghan government will agree.

There are also questions about whether Taliban fighters loyal to hardline Islamist splinter groups will be willing to adhere to the reduction in violence agreement.

Some senior commanders of the Taliban who arrived in Doha for the signing ceremony said they will ensure that the US and Afghan governments accept all the conditions laid down by the group that controls about 40% of Afghanistan, according to Afghan defense officials.

Sources in the Taliban earlier this month said they were prepared to launch a spring offensive and had recruited more than 6,000 fighters and suicide bombers if the agreement collapses.
