Russell did not believe that Armageddon was the destruction of all. Witness doctrine on Armageddon is a product of an article by Rutherford in 1929.Russell believed that Armageddon was a period of anarchy following the end of gentile times when socialistic labor would turn against capitalistic governance. Chaos would ensue, eventually turning people to god's kingdom as expressed in a restored kingdom with its capitol in Jerusalem. Neither Russell nor modern Witnesses believe Armageddon means the end of the world.
As I said before, Time is at Hand was NOT Russell's first book. First in the Millennial Dawn series is Plan of the Ages, an update to Russell's Food for Thinking Christians. I own these and have read them many times.
I own and have read many times virtually everything Russell ever wrote. Its my job. I write history. I'm the coauthor of a major work on the Russell era.

It is you who are mistaken. Almost everything Russell wrote is available on line. I suggest you confirm your view or give it up. Let me put it to you bluntly. Cite the reference to Russell's work that proves your point. Inform yourself.
