I have planned many a NEO and executed quite a few of them in all sorts of places. I also happened to be amongst the first in AFG in the autumn of 2001 and enjoyed Christmas dinner that year at Bagram, when it was basically nothing but mines and Soviet scrap.
Whilst some of my planning involved some out-of-the-box thinking I must confess that none of my plans started with the sudden evacuation of all military assets first, before finally turning my attention to all those pesky non-combatants left behind.
The US has in recent days managed to fly in a few thousand troops, some of whom had only just left, yet are still vastly outnumbered by the US citizens still stuck places various around Afghanistan. This is way beyond leaving your house and carelessly forgetting your wallet. This could be the prelude to the biggest loss of US citizens since, or even exceeding, the terrible events of 9/11.
