COVID-19 is the climax to this 4T

[Ldr]

It's easy to see from the stat below that in the US the divide begun around 2008, not after 9/11, since the ideological divide was still tolerable in 2004.



In the UK, where they are experiencing their first real 4T in almost 500 years (because they ruled over colonies, basically lifting all citizens above the colonists), the 4T begun around 2012.



Just check out my generational hormone theory where I've explained how this is due to increasing hormone levels of dopamine (increasing in-group coherence) and vasopressin (increased territoriality and aggression). It's the increasing dopamine levels at the beginning of a 4th turning either unify or divide a nation. This time around the ideological polarizations were pretty high around 2008, thus two separate in-groups are diverging further from each other every year. This is the very same situation that happened before the US Civil War. And in 1930 the political polarizations were low, so the increasing dopamine levels unified the nation pretty well, and the threat of Nazi Germany further galvanized the US under a common threat.

This same increase in group coherence and territoriality can be observed in animal population cycles during the last quarter/turning. And once their first quarter comes to an end, the group coherence and territoriality loosen, and this is basically the 1970s, lemming style.
