Gulags are typically not highly manned by seasoned troops. Our CIA should make an effort to subvert and arm them and plant the seeds of rebellion.
You'd have to read Escape from Camp 14: Blaine Harden to see how relatively impossible it would be. It's a fine study of how the camps differ with inmates and how they're unaware of almost anything that you or I would be aware of. It's an incredible book.
It would be virtually impossible to invade their camps.
Highly moving. I hope they make a film out of it, but Hollyweird is too busy making 3D garbage and stupid-ass films.
