No doubt Biden totally goofed up the Afghanistan evacuation and for this, he deserves not to be re-elected. However, to put the record straight, it was the Trump administration that went behind the back of the then Afghan government and struck a deal with the Taliban. That’s why Taliban walked in into Kabul without a shot being fired. In fact the Taliban nor the American forces fought each other.
Coming back to Biden, the guy is just a compromised puppet - a useful idiot.
