Your report from Kabul (International, 16 May) recalls a visit to Afghanistan in 1996 to advise on a health programme.
Abandoned Soviet tanks, which had had all their moveable parts removed, were turned upside down and used as bridges over small ravines.
I was interested in your note that Afghanistan’s fledgling steel industry has only five working mills.
Does Scotland, with a history of major steel and related industries, have any? Maybe independence will allow us to restart steel manufacture at least sufficient to meet our own needs and/or to sell specialist steels worldwide.
