Europe’s experiencing the longest hot war since World War II. The war in the Gulf seems to be escalating as we speak. Extremism has been on the rise for years now. Is it actually getting worse or is it simply the fact that we can access information from all four corners of the world so easily as never before?
Yes, there was a long period of post WWII stability, though there were still lots of problems including the Cold War that ended by 1990. Then there’s also been a series of slowly escalating Middle East conflicts. I think a lot of people are pointing to that period 1990-2001 or so with no “major” global conflicts happening. But even then, there was genocide in Rwanda. But the information/reporting was less global at the time.
It was always volatile. It’s more volatile lately than 30 years ago, but if you go farther back I don’t think this is unusual.
