A question to stewart about "Bombs Away"

[s_trangedays]

Hi Stewart; when you mentioned "unpaid bills in afghanistan hills"in your song called bombs away, do you refer to anything in particular like 'terrorist' traning camps there? or did it have to do with russian invasion of the country...even though I am not sure if camps where there at the time when the song was written, but I am listening to this song for last 20 yrs and I wonder what does it refer to. Thanx
