They never tried enough. Its not worth fighting for such a place. They used them anyway to further their objectives in the larger scheme of things and now you can see afghanistan as the most backward place in the whole of Asia.
Well, you chose my selected sentence. Don't know but assume you agreed with other part of my post.

You said "they used them anyways"....how??
