My heart goes out to citizens of Afghanistan and personnel who are stranded and suffering in this endless conflict.
US was going to withdraw from the region, it was known and negotiated for many months.
It's immaterial whether USA's assessment of Taliban's strength was wrong or deliberately misleading.
This hasty poorly planned withdrawal of troops, closure of US embassy will send spine chilling signal to US allies all across the world from Ukraine to Taiwan to Japan.
This sudden change of events will weaken US brokered peace in middle east, embolden China in South East sea
