DW and I had this conversation a few days ago. Man has always been violent, from the very beginning. In Biblical times, people were slaughtered by the thousands, how many Jewish people died at Hitlers hand, 800,000 people in Rwanda in just 100 days in 64, and the list goes on and on. TV coverage plays a part also, when I was a kid people killed each other, it just wasn't publicized on 24/7 media circuses.
Then there's the book of Revelations......are we nearing the end of time???? Quoting from an article I read by the EU Commission back in 2022, archaeologists have characteristics they look for that signal the decline of civilisations - disruption to trade routes, shifts in supply and demand, disease, environmental degradation, and extreme political dysfunction. Any of those sound familiar?
