After the US and Taliban Doha agreement in 2020, the Taliban were given political legitimacy. And they had major political and material support from regional countries, including Pakistan and Iran. The ending of US combat operations, and restrictions put by Doha agreement on the ability of Afghan forces to go on the offensive, allowed the Taliban to control more ground and launch major assaults across the country. The fall of Afghan Republic is mainly caused by political mistakes made in Kabul and Washington. The Afghan military fought bravely and fought hard and our people honour that.
As the result of the Taliban back to power in 2021, they brought back Al-Qaida to Afghanistan, who had been diminished during the two decades Afghan and US military pressure on them. The leadership, including Ayman Al-Zawahiri, his two deputies, and members of Al-Qaida global council, were once again protected by the Taliban in Afghanistan.
