At best, Biden administration’s accounting of the disgraceful American exodus from Afghanistan is a disappointment. At worst, its attempt to dump most of the blame for the debacle on the Trump administration is a disgrace. That’s not to say that the charge against the previous administration is trumped up. The Doha Agreement that Donald Trump cut with the Taliban and his decision to abandon Afghanistan posthaste not only was impatient; it also was imprudent, ignorant and idiotic.
