Here is how Undaunted Danny defined Watchtower's doctrine of "God's Kingdom":
"Rutherford dumped holidays, birthdays and the 1874 date for the invisible return on Christ, and invented an ?earthly class? of Witnesses, since only 144,000 can go to heaven in their teaching. The rest, meaning all 99.9% of Witnesses still alive, will live forever on a cleansed earth, under the rule of the Watchtower leaders in heaven, who will keep them in line by local elders known as ?Princes.?"
The only thing that is missing here is the casual lip service paid to Jesus and Jehovah, but still this is the most succinct and truthful definition of the core WTS doctrine I've seen so far.
Thank you Danny,
