There was this circuit assembly talk:
And here are some choice quotes from that talk published in newspapers at the time:
"Some of the questions creating eager anticipation among the delegates are: Can there truly be a world conqueror? How? And what may the mid 1970s bring?" (Red Bluff Daily News, 9/11/1970, p. 5)
"Bible chronology and world events point to the mid-1970s as the possible time when all human preventers of peace on earth will be eliminated" (Tuscaloosa News, 10/17/1970, p. 2; Ruston Daily Leader, 1/22/1971, p. 4).
"All indications are that the conquest of the enemies of peace will take place within this generation. Bible chronology confirms this fact" (L'Avenir, 10/15/1970, p. 25; translated from French).
"All the evidence indicates that all enemies of peace will be vanquished within our generation. This is substantiated by Bible chronology" (The News, 11/12/1970, p. 6; this is obviously the same statement as the preceding quote).
"Men who know the trend of world affairs, and more importantly, the Bible itself, earmark the 70's. . . This is a decade of destiny and as Christian Witnesses of Jehovah, we can conquer the world as Jesus did by our faithfulness to God's Word, the Bible" (Burlington Times-News, 9/29/1970, p. 8B).
"Our lives are involved for then we will be either on the side of the conquerers or among the dead conquered ones. So who will conquer the world in the 1970s? You will if you by faith stick to God's Word and do His will now you will thus be rewarded with eternal peace in a new system of things on earth" (Chillicothe Constitution Times, 11/9/1970, p. 1)
