awakening,
ummm IMO ...WWI & WWII do have relevance. But the JW 2520 numerology lore is clearly exposed as false; primarily because Jesus is seated on the throne when he was resurrected in 33 AD. Ac 2:17-34 And secondly, Darius I (Persian, 1 st regnal is 522 BC) is the king ruling when Israel's "desolation and fasts" end in 517 BC. Zec 1:5-7, 7:1-12 -see Jonson's GTR
However, in the 24 th chapter of Matthew you have three markers that lock down Jesus second coming, 1) WWI & WW II ("nation against nation and kingdom against kingdom"), Mt 24:7 2) Noah's "flood came" in 100 years Ge 5:32; 7:6; Mt 24:37-38 , and 3) the "evil slave" appearance. Mt 24:45-51 Behavior of this "evil slave" e.g. drunken obsession with the master's delay, with authority to inflict vigilante pummeling of fellow slaves, and using God's personal name Jehovah in an illegal profane way fits unmistakably the JW GB profile as something "evil", displaying the spirit of Judas. This is replaced by a "faithful" slave.
So, arguably it is plausible that 1914 WW I starts unwind of a 100 year generation. And, medical technology miracle drugs etc., stretches that generation to sync with Noah's 100 year timeline so that approximately 450,000 centenarians will be living in 2014. -see Website: The Centenarian
