Years ago, James Schlesinger noted that human beings have only two operational modes: complacency and panic. It is an observation that rings true and that we can generalize in terms of groups: some humans are catastrophists, and some are cornucopians. I tend to side with the catastrophists, to the point that I created the term "Seneca Effect" or "Seneca Cliff" to define the rapid decline that comes after that growth stops. Indeed, catastrophes are a common occurrence in human history, but it is also true that sometimes (rarely) a catastrophic decline can be reversed: I termed this effect the "Seneca Rebound." 

Less than a week into the war, it seems increasingly likely that Vladimir Putin is heading towards a historic defeat. He may win all the battles but still lose the war. Putin’s dream of rebuilding the Russian empire has always rested on the lie that Ukraine isn’t a real nation, that Ukrainians aren’t a real people, and that the inhabitants of Kyiv, Kharkiv and Lviv yearn for Moscow’s rule. That’s a complete lie – Ukraine is a nation with more than a thousand years of history, and Kyiv was already a major metropolis when Moscow was not even a village. But the Russian despot has told his lie so many times that he apparently believes it himself.
