Financial Tribune - The United States signed a landmark deal with the Taliban on Saturday, laying out a timetable for a full troop withdrawal from Afghanistan within 14 months as it seeks an exit from its longest-ever war.

The agreement is expected to lead to a dialogue between the Taliban and the Kabul government that, if successful, could ultimately see an end to the grinding 18-year conflict, news wires reported.

Taliban fighter-turned-dealmaker Mullah Baradar signed the accord alongside Washington�s chief negotiator Zalmay Khalilzad, at a gilded desk in a conference room in a luxury Doha hotel.

The pair then shook hands, as people in the room shouted �Allahu Akbar� (God is greatest).

US Secretary of State Mike Pompeo looked on as the two inked the deal, after urging the insurgents to �keep your promises to cut ties with Al-Qaeda�.

On the eve of the signing, President Donald Trump urged the Afghan people to embrace the chance for a new future.

�If the Taliban and the government of Afghanistan live up to these commitments, we will have a powerful path forward to end the war in Afghanistan and bring our troops home,� he said.

But the position of the Afghan government, which has been excluded from direct US-Taliban talks, remains unclear and the country is gripped by a fresh political crisis amid contested election results.

The Doha accord was drafted over a tempestuous year of dialogue marked by the abrupt cancellation of the effort by Trump in September.

The United States and its allies will withdraw all their forces from Afghanistan within 14 months if the Taliban abide by the terms of the accord.

After an initial reduction of troops to 8,600 within 135 days of Saturday�s signing, the US and its partners �will complete withdrawal of all remaining forces from Afghanistan� within 14 months.

Since the US-led invasion that ousted the Taliban after the September 11, 2001 attacks, America has spent more than $1 trillion in fighting and rebuilding in Afghanistan.
