I'm confused as to your first two citations and the year they are from.
My understanding, throughout the 1970s, was that the "great tribulation" would unfold in the following manner:
- The United Nations would announce that there was worldwide "peace and security".
- Right after that the UN would lead an attack upon "Babylon the Great" (All religions but the Jehovah's Witnesses).
- After the destruction of all religions the UN would notice the Jehovah's Witnesses as the last religion left standing and would direct its attention towards them.
- When it seems that the Witnesses are about to be wiped out Jesus and company will come down and destroy the nations of the Earth in the battle of Armageddon.
