Trump’s newly empowered foreign policy led to the Doha agreement with the Taliban and America’s final defeat in Afghanistan. The Taliban’s principal demand and the central element of the eventual Doha agreement was the full withdrawal of US forces from Afghanistan. It was hardly something the Taliban needed to demand because Trump was demanding it too. Trump was not inclined to enforce the agreement anyway. Trump campaigned on getting out of Afghanistan and repeatedly and publicly announced his intent to withdraw, which undermined negotiations just as much as Obama’s timetable had done.
