In allusion to the "100 years" that you are mentioning, I recall reading one Avyakt Murli (1969) where 100 years is mentioned, as when in Bhakti it is remembered that "Brahma lived 100 years." I don't recall exactly what it said. However, it is "believed" that the Confluence Age lasts 100 years. The question is:
when did it start? Here comes the speculation which is not knowledge. Some "believe" it started in 1876 (when Dada Lekhraj was born) thus, they thought the end of the Confluence in 1976.
Some believe that the Confluence starts in 1936-37 when the Supreme Soul enters Dada Lekhraj at that time. Thus, adding 100 years to it, you come up with 2036-2037 to end the confluence. "But" in Bhakti they talk about "Brahma." When Dada Lekhraj becomes "Brahma"? or when "Brahma becomes Vishnu?" there is no specific date for that. There is no specific date as to when God entered him. There is no specific date as to when Dada becomes Brahma. It is obvious to me that a student does not become a medical doctor the first day of classes...and as everything in this drama, changes happen as subtly as when night time turns into daylight.
As far as the duration of The Cycle. It is 5000 years.
As far as the war between USA and Russia, take a look at the links below. It is worthwhile to mention that Russia became as such just in recent times. Before it was known as USSR (up to 1991). To be specific.: No, I haven't heard any Murli when both countries are mentioned.
