Alarmingly, one of the biggest breakdowns in ancient times, at the end of the Bronze age, now seems to have given rise to the &#x27;sea people&#x27;, a band of refugees that roamed and pillaged.  There was a chain reaction of famine, revolution, refugees spilling over to neighbors who also had a poor crop, more famine, more revolution. In an expanding circle of fire, most known civilizations fell in just a few years and produced an enormous army of armed refugees.  They only stopped when Egypt armed everybody and killed them all. Even then Egyptian society was so disrupted (by arming civilians, seeing their god-kings bleed, fragmentation and slow rebuilding) that it took a century to have a unified government again.<p>I see some parallels in our modern world. We have a slash-and-burn air-assault style of war that leaves millions homeless and infrastructure in ruins. Refugees are mounting alarmingly. At some point, they&#x27;ll become &#x27;sea people&#x27; and we&#x27;ll all have a hard decision to make.
