Not at all. Nor Native American killers, nor British killers, nor Mexican killers, nor German killers, nor Italian killers, nor Japanese killers, nor Korean killers, nor Chinese killers, nor Vietnamese killers, nor Serbian/Croatian killers, nor Iraqi killers or any others who justly or unjustly make war one upon another. But historically, once the fighting stops and peace is established, prisoners of war are released.
Trump released the Taliban fighters on condition that the Taliban that had stopped fighting and with a more democratic Afghan government in place on condition the Taliban make no more war. If they reneged on that agreement, retribution would be swift, certain, deadly. They believed him.
As it turned out, they did not fear or respect Biden who reversed almost all Trump policies and they risked testing him. When he did nothing to stop them they again made war.
