Not all Afghanistan men were trained, or armed, to fight the Taliban. This blanket accusation against all the men is - my opinion - unjust. Those that were appear to lack the confidence to carry on without the foreign forces to lead them; their own PM left, where was the leadership to come from?
The withdrawal of US/UK etc troops looks to have been very badly planned and I sincerely believe that our PM and Joe Biden have been given poor intelligence in how things would play out.
I'm so disappointed in Joe Biden, that speech last night has gained much approval from the general US population with his continued reference to how much money has been spent (not invested, spent) in Afghanistan, how keen he (Biden) was to not pass this on to another President (Biden is 7 months into his 4 year role so what was that supposed to mean)? It's very fair to say that this wouldn't/couldn't be a lifetime commitment for US troops to be deployed to Afghanistan, but the departure has clearly been done before the Afghanistan people were ready to take over the running of their own country.
