That's the thing about prophecies, they are always true. So when the bad thing eventually happens, the prophets can say "I told you so".
There was an article a few days ago about the scientists warning about coronavirus. The article mentioned they've warned about this since the 70s and SARS a few years ago, and how bad and evil it is to not be completely prepared for this eventuality. They will eventually be right but we can't have firefighters stationed in every house or ambulances follow every car just in case.
The hospital I work at had protocols for massive outbreaks for decades. They didn't apply because they were for things we know about like Ebola, not for a virus that spreads through the air because every airborne virus we knew about prior including SARS wasn't nearly as deadly and transmissible (which makes some people believe it was engineered after all).
The Bible prophecies in the NT are likewise intentionally vague and have been fulfilled in Nero burning down Rome, the fall of Jerusalem and every large conflict since. Pestilence and food shortage and calls for peace following war has been true since time memorial, only in the last 100-200 years has the world been made rich enough for certain aspects of that to no longer be true the way it was before. This makes the JW prophecies less and less relevant. Iraq didn't have food shortages and pestilence like they would've had in the past after a war because as the US was fighting, they also brought with them the tools of rebuilding a free and democratic civilization which are the precursors to wealth and wellness. As war gets more and more "humane", the effects will diminish as well.
