President Joe Biden delivered remarks Thursday evening on the terrorist attack Hamid Karzai International Airport, delivering a stern warning to ISIS-K. "To those who carried out this attack, as well as anyone who wishes America harm, know this: We will not forgive. We will not forget," he said. "We will hunt you down and make you pay." Biden says he bears the “responsibility” for the attacks outside of the Kabul airport that killed 12 U.S. service members and wounded others, the first casualties in Afghanistan since Feb. 2020. "I bear the responsibility, fundamentally, of everything that's happened of late,” Biden said. Biden noted that former President Donald Trump made a deal with the Taliban that if the United States got out service members by May 1 of this year, the Taliban would not attack U.S. troops. The president also signaled that he's willing to send in additional forces but suggested the U.S. military was behind his plan to withdraw all troops from Afghanistan by the Aug. 31 deadline he set. "I've instructed the military, whatever they need — if they need additional force — I will grant it," Biden said.
