Were JWs Right That There Would Be A Time When Governments Would Go After All Religion?
No.
The JW claim was that governments would turn on all religion, making it "devastated" and "naked."
Religion is too basic a human need for that to happen. Sure there are authoritarian regimes here and there and people who dislike religion in all forms here and there, but the idea of it happening around the world is ridiculous.
Imagine how that idea would play out with any of the three Abrahamic faiths, for example. Christians, Muslims and Jews have happily died for their religions for thousands of years. Imagine how the idea would be received in the Middle East, where the distinction between government and religion is debatable.
