It's amazing how we keep discovering lost man made projects, even from quite recent times. I came across this on Stalin's Transpolar Railway, I'd never heard of it before and is as amazing a story as the Great Hedge of India was when I first heard of that not so long ago.
The problem with this sort of discovery, is that there are perhaps quite a number of people who know or knew about it, but for one reason or another have never made it public. And this doesn't just effect Russia, but many other countries as well.
We still have parts of concentration camps left from these moment of time, yet some people think that this should not be part of history, because it doesn't involve them. Yet history was based on such events happening, and some people do not put much or any importance to it.
Recently there was a documentary on television regarding Hitler and the other Nazi officer's of that time. The documentary involved the grand-children of some of those officer's, and how those grand-children were trying to come to some solutions of how they may have seen 'two-sides' to the stories that have unfolded. It was a very interesting and moving documentary, and one that needed telling?.
