Never could figure out why, buildings, weapons etc, are not blown or destroyed upon leaving a combat zone. Even our embasey should have been destroyed.
They left people behind, what makes you think they care about equipment?
I'm not just talking about this arm pit, Southeast Asia when we pulled out, Turkey when the military took over some of the bases, Iran when the Shah was disposed that I know of, probably many other places I don't know of.
I don't know if the people who were left behind were private contractors, or not, if they were then let the company that hired them, get them out.
If not then a stone shouldn't be left unturned to get them out, by any force necessary.
