The strategy he outlined is for everyone to not support in any way anything they know to be untrue.

In The Gulag Archipelago he lamented if only we had jumped and killed every Soviet government agent who came in the middle of the night to take away our men and other loved ones then things would have been different because the agents would've been much more circumspect in coming at all. He recognised that that was much easier said than done. "Live not by Lies" was written after that.

I only read the first part of Archipelago. I did finish 200 Years Together.
