I could speak for hours about Viktor Suvorov...what you are thinking about "icebreaker" book - is Suvorov properly compelling facts in your opinion? - for many of his thesis sounds at least plausible..
Briefly and in my humble opinion. He was right in his principle thesis but made plenty of errors, some technical, some logical in his first book. Not completely his own fault since he did not have access to the Soviet archives. It was like the discovery of Neptune - the mathematical prediction before the factual observation. He was criticised, laughed at, etc. Ironically, later on, many of his Russian critics silently agreed with his thesis about the Red Army preparations in 1941.
