The leaders of Afghanistan have played Bush, Obama, Trump and Biden as marks. Through corruption they made a fortune from the US playing along with the US fantasy of this functioning Afghan government. They were always ready to pack up and run with the profit when they needed to.
Trump who has played the US as a mark might have been a little more aware of that then the other presidents. He knows about con jobs. He didn't even bother to include the Afghan government when he negotiated our withdrawal from Afghanistan. Its like he knew they were not a real government so he didn't give them the time of day. He announced the time table for the withdrawal to give the Taliban plenty of time to plan their current take over. Than he drastically reduced our troops knowing that that would further weak the Taliban government.
But none of it matters because we were simply conned by the Afghan government.
But members of the Trump cult will forget about all this and just blame Biden. The cult has been quite happy and vocal. After years of losing they think they have something to smile about.
