• US, Taliban reduce violence ahead of an agreement
• Doha sets the stage for an agreement aimed at bringing peace
• Pompeo arrives to witness the signing ceremony
• Esper visits Kabul to meet Afghan president

KABUL/DOHA: US Secretary of State Mike Pompeo arrived in Qatar on Saturday to witness the signing of a historic deal with Taliban insurgents that could represent a step toward ending the 18-year-war in Afghanistan.

While the agreement paves the way for the United States to gradually withdraw its troops from a conflict that has become America's longest war, many expect that talks to come between the Afghan sides will be far more complicated.

Pompeo arrived in the Qatari capital Doha from Washington. The deal will be signed in the afternoon by US special envoy Zalmay Khalilzad and Taliban political chief Mullah Abdul Ghani Baradar.

US Defense Secretary Mark Esper meanwhile travelled to Kabul on a visit that officials and experts said was aimed at reassuring the Afghan government about the United States' commitment to the country.

For US President Donald Trump, the deal represents a chance to make good on his promise to bring US troops home. But security experts have also called it a foreign policy gamble that would give the Taliban international legitimacy.

"Today is a monumental day for Afghanistan," the US Embassy in Kabul said on Twitter. "It is about making peace and crafting a common brighter future. We stand with Afghanistan."

Hours before the deal, the Taliban ordered all its fighters in Afghanistan "to refrain from any kind of attack ... for the happiness of the nation."

"The biggest thing is that we hope the US remain committed to their promises during the negotiation and peace deal," said Zabiullah Mujahid, a spokesman for the hardline Islamist group.

Mujahid said it was "irritating and provocative" that foreign military aircraft continued to fly over Taliban territory, but militia fighters were following the order to stand-down.

For millions of Afghans, the deal represents some hope for an end to years of bloodshed.

"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 Afghan 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.

UNCERTAIN PROSPECTS

But prospects for peace remain uncertain given the next step is reaching agreement with the Afghan government.

Senior members of the Afghan government and countries surrounding Afghanistan have been concerned that the United States could abandon Kabul much like it was perceived to have left the region after the Soviet Union exited Afghanistan decades ago.

The accord also comes amid a fragile political situation in Afghanistan. The Independent Election Commission said on Feb. 18 that Ghani won a September 28 vote beset by allegations of rigging, technical problems and other irregularities.

Afghanistan Chief Executive Abdullah Abdullah rejected the results, claimed to be the victor and vowed to name a parallel government.

Michael Kugelman, deputy director Asia Program at the Wilson Center, said of Esper's trip to Kabul that "Washington is essentially trying to show that its full strength is behind this deal and it wants to also indicate to Kabul that it's fully behind Afghanistan as the peace and reconciliation process moves toward a formal beginning."

"(Esper's trip is) perhaps an indication that the US is ready to essentially accept the new government in Afghanistan," he added.

The war, which has killed tens of thousands of people, began when the United States launched attacks on Afghanistan just weeks after the September 11, 2001, attacks on New York and Washington by the Afghanistan-based al Qaeda militant group.

Washington accused the Taliban of harbouring al Qaeda and its leader Osama bin Laden, and with its allies ousted the group from power. But the Taliban has remained a potent force and currently controls about 40% of Afghan territory.

TROOP WITHDRAWAL

Trump said in a statement on Friday said the deal 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.

A joint statement released by the US and Afghan governments on Saturday said the United States and NATO would withdraw all troops in Afghanistan within 14 months if the Taliban upheld its commitments.

Foreign ministers and bureaucrats from Pakistan, Indonesia, Uzbekistan and Tajikistan arrived at the venue ahead of Saturday's signing ceremony at the Sheraton hotel in Doha.

Pakistani Foreign Minister Shah Mahmood Qureshi said his country wants a "responsible withdrawal" of US troops from Afghanistan.

Under the deal, the Taliban wants 5,000 fighters to be released from Afghan-run jails, but it is 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 in Doha for the signing said they will ensure that the US and Afghan governments accept all the conditions laid down by the group, according to Afghan defence 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.
