When Biden took office there were only 3500 US soldiers in country mainly guarding various US buildings around Kabul. The so called peace accords where there was suppose to be a power sharing agreement between the Taliban and the Afghan military were brokered under Trump . Actually all US forces were suppose to be out in May . Trump was the one who gutted us forces in the region.
Unless your mad Biden didn’t escalate the war by pouring tens of thousands of soldiers in the country when the Taliban started to break the peace accords , I can hardly blame his administration.
