Trump chose to use a national cemetery as a backdrop for his propaganda campaign.
Trump was the one that signed off on the whole Afghanistan withdrawal deal. Trump agreed to leave all that equipment to the Taliban, he agreed to withdraw all American troops on the sole condition that the Taliban did not attack Americans evacuating Afghanistan.
Trump left Biden with the task of actually withdrawing. Taliban lived up to their word, they did not attack withdrawing troops or civilians, No one in history has ever evacuated more people in a shorter time than was done under Biden. The bomb that killed people at Abby Gate was set off by a group that was unaffiliated with the Taliban.
Trump left office with so few troops in Afghanistan that Biden had to send more just to facilitate the withdrawal.
If Abby Gate was a disaster, it was Trump's effing fault!
