Biden's not arsed as he's a one-term president. That's even if he makes the full term due to his health.He clearly will carry some measure of blame. No question. No one is arguing otherwise. Not sure why you think he's not arsed.
There was no consensus in the intelligence community in the US or elsewhere the Afghan government and military would collapse in a matter of moments. Suggesting they "sat" on the intel means you believe the US lied to her Allies about what they believed to be the most likely scenario and knowingly put US and Allied assets at risk. This may be your assumption but it's not based on clear and compelling evidence that I've seen. You referenced "rumours".
More than 70,000 have now been evacuated from Afghanistan.
Rumours - yes at the moment. Hopefully the truth will out in time.
Yes 70K evacuated against a backdrop of tens of thousands of Afghans - crushed up against the barricades of HKIA, people clinging to aircraft and falling to their deaths. British military having to exfil special forces teams cut-off and surrounded in Kandahar.
It's thanks to the bravery and expertise of the troops on the ground combined with the tactical planning of the airlift commanders that 70K have been evacuated - it has very little to do with the politicians and the bean counters in Washington and London.
Once again the military bale out the political establishment
