The passage obviously fits the JWs to a tee. The Watchtower has published books like The Time Is At Hand and The Kingdom Is At Hand, which clearly key off Luke 21:8.
Here is a partial list of books and booklets that violate Jesus' command in Luke 21:8:
"The Time Is At Hand"
"Universal War Near"
"The Kingdom Is At Hand"
"World Conquest Soon -- By God's Kingdom"
"The Kingdom of God is Nigh"
"Man's Rule About to Give Way to God's Rule"
"Take Courage -- God's Kingdom Is at Hand!"
"The Approaching Peace of a Thousand Years"
"God's Kingdom of a Thousand Years Has Approached"
There are thousands of statements in various Watchtower publications along the same lines.
In 1994 I had the opportunity to challenge GB member Albert Schroeder about Luke 21:8. I had called him one Saturday morning to discuss why he had failed to answer my letter he had promised to deal with nine months earlier. I asked him to read the passage, then confirmed that he understood what it meant. Then I asked him why he thought it doesn't apply to JWs. He hemmed and hawed for about five minutes, but I pressed on. He finally said, "You're not going to let go of this until I answer you, are you?" This in itself ought to tell readers exactly what kind of lying hypocrites these people are, his hoping that by stonewalling he could put me off. I said, "No." He said, "It CAN'T apply to us, because we're God's people!"
