When they deny everything and the dangers ahead, they come up with excuse after excuse, and then plead innocence and yet blame the forewarners for not forewarning them.
The Revelation was written for people who were alive at the time. Forewarners have been forewarning for two thousand years and all of them have been wrong. So yeah, it makes sense to question your forewarning.
If you want people to take your forewarning seriously, you'll have to show some reason to think that the Revelation applies to us and only us. So far, all you've done is preach the same old same old that has been wrong every time. Stop crying wolf and show us the wolf.
Anybody can predict that there will be wars and rumours of war. That's no more remarkable than predicting that the sun will rise tomorrow. But very few "prophecies" are specific enough that fulfilment can legitimately be claimed. It's easy to say that such-and-such an event "fulfilled" such-and-such a prophecy AFTER the fact. Get it right BEFORE the fact and somebody might be impressed.
