I checked history and could not find any mention of Roman armies ever using the Babylonians to destroy anything.
Or not.
Or maybe Habakkuk thought the event would be in his lifetime.
Or maybe the author of Matthew was mistaken about being in the 'final phase'.
Or maybe that was also a mistake.
My paternal grandparents were Jehovah's Witnesses in the early 20th century, when the Watch Tower Society predicted that the world would end (Armageddon) in 1914. The beginning of WWI gave them hope. Later on, they predicted the completion of Armageddon by 1975 (6,000 years after when they thought man was created). They were just as confident about the biblical predictions then as you are now and just as wrong.
ETA: My grandfather died earlier than he should have because he couldn't allow doctors to give him blood transfusions. By that time, he had given up hope of seeing Armageddon, but he still clung to his beliefs. He died in the 1960s.
Right, the Roman armies did Not use Babylon but God did
God used the Roman armies to destroy unfaithful Jerusalem in the year 70
God used the Babylonian forces under Cyrus in 539 BCE
I don't see how Matt. 24:14; Acts 1:8 is mistaken because the international work is now done on a global scale
What ended in 1914 was peace on earth (WWI then WWII) the 'start' of the global pangs of distress - Matt. 24:7-8
Matthew 24 has both a minor and a major fulfillment and so does Luke 21 - Luke 21:11
The 'final signal', so to speak, is still ahead of us as found at 1st Thessalonians 5:2-3
As Proverbs 4:18 brings out that spiritual light would be gradual. Understanding improves over time - Daniel 12:4,9
What was thought in the past does Not make the Bible as wrong, just the understanding at that time.
So sorry to read of the long loss of your grandparents. May our Heavenly Father bring comfort to you

We know your grandparents will be awakened from death's deep sleep because they will hear Jesus' voice to awaken them just as Jesus had resurrected people while on earth back to happy and healthy life - John 11:43; John 6:40,44
