 So that task of evacuating Afghans at risk really started from the point that we'd worked with Afghans for 20 years on that campaign. Of course, military interpreters, members of the Afghan military, people like women judges... People therefore seen as the enemy by the Taliban. But people who we had relied on and who'd relied on us to deliver what we were there to do. That was the job. So if you strip away all of the noise and the detail from that, that was what we needed to do.
