As the Taliban entered Kabul, the country's president fled without a word.

Then a former leader, Hamid Karzai, stepped in from the shadows -- and it appears he is following his old playbook of traditional tribal deal-making.

The 63-year-old former president was once the fresh face of the new Afghanistan following the September 11, 2001 attacks, when he was plucked from relative obscurity and hailed as the modernizing force with tribal ties that could transform the crippled nation.

As a fluent English speaker, tribal elder and hailing from a prominent Pashtun family, he seemed to have guaranteed influence.

He eventually fell out of favor in Washington, however, and into the political wilderness, with his former finance minister Ashraf Ghani taking the reins in 2014.

Full circle

Fast forward to August 2021: with the hardliners back in control, and with Ghani in the United Arab Emirates, Karzai has been seen in a familiar role, shuttling between meetings, invariably looking for allies in what will likely be a small window to hammer out some kind of agreement with his old foe.

As the Taliban entered Kabul on Sunday, Karzai appeared in a video shared widely on social media, with his daughters by his side asking them to help save Afghanistan together.

"I would like to inform Kabul residents that my family and I, my daughters, are all here," he said.

"I hope the country's problems are solved through talks and negotiations," he said, striking the pragmatic tone he was known for during his years in power.

"I also ask all the security forces and the Taliban forces, wherever they are, to protect the lives and properties of the people and focus on the security of people."

Then on Wednesday, Karzai sat down with a Taliban delegation that included Anas Haqqani -- the scion of the infamous Taliban faction that unleashed havoc with suicide bombs and brutal attacks on Kabul when he was president.

Things have come full circle.

'A unifying figure'

In December 2001, following the ousting of the Taliban, Karzai was appointed chairman of a transitional administration at UN-sponsored talks in Bonn, Germany that pledged to work towards democracy.

A traditional Afghan assembly then confirmed him as president of the transitional government paving the way for his leadership of the newly minted republic.

But criticism soon overshadowed the initial plaudits that showered Karzai, and even earned him a nomination for the Nobel Prize.

Claims of electoral fraud tarnished Afghanistan's second presidential election with Karzai declared the winner of the vote after challenger Abdullah Abdullah abandoned a run-off.

The election of Barack Obama and the exit of his former patron George Bush set the stage for a nasty showdown, as the US launched a massive "surge" and deployed more than 100,000 troops to Afghanistan to beat back a rising Taliban threat.

For years, Karzai warned that the heavy-handed counterinsurgency in the Taliban's southern strongholds was only reviving the movement and begged Washington instead to focus their efforts on bringing Pakistan's support for the militants' exiled leadership to heel.

Even as the insurgents bombed his capital, Karzai insisted that the Taliban must be brought into the fold, drawing harsh criticism when he called the militants "brothers".

But his requests were largely ignored.

He eventually lost the support of the West, with American officials and the media routinely pillaring him for corruption even as the US dumped billions into an impoverished, agrarian economy that was overwhelmed by the deluge -- making graft all but inevitable.

After finishing his second term, Karzai lost power to Ghani.

"If we are going to see a political solution, Hamid Karzai was going to have to play a key role in it," Ibraheem Bahiss, a consultant with the International Crisis Group.

"He's a unifying figure in many ways," he added, highlighting Karzai's reputation for uniting "disparate factions" during his presidency.
