Celebratory gunfire resounded across the Afghan capital on Tuesday as the Taliban took control of the airport following the withdrawal of the last U.S. troops, marking the end of a 20-year war that left the Islamist group stronger than it was in 2001. Shaky video footage distributed by the Taliban showed fighters entering the airport after the last U.S. troops flew out on a C-17 aircraft a minute before midnight, ending a hasty exit for Washington and its NATO allies. “It is a historical day and a historical moment,” Taliban spokesman Zabihullah Mujahid told a news conference at the airport after the departure. “We are proud of these moments, that we liberated our country from a great power.” The Taliban’s shockingly quick seizure of the country coupled with the West’s hurried departure has resulted in the terrorist group acquiring a hefty arsenal of weaponry and equipment, left behind by fleeing Afghan forces. U.S. officials have estimated that $83 billion worth of weaponry and equipment had been invested in the Afghan force, but have not been able to say how much of that has fallen into the hands of Taliban fighters, post-takeover.
