I’ve been around since the 70s and I mostly agree … but on one point I disagree … the ability of humanity to wipe itself out with a nuclear exchange. Back then, even 20, 30 years ago there were a lot level headed leaders who (although we may have disagreed with them) were less radical and would be less likely to consider launching a nuclear weapon for any reason. Back then, we also had a lot of actual war veterans in the public and in government who understood the nature of war … now there are fewer of them around. Most people including those in government now don’t know what war is any more, other than to see it glorified in history books, movies and pop culture.
So the combination scares me … a society that is complacent to war yet has the weapons to cause world wide destruction if someone disagrees with them.
