There are so many angles to think through on this and having a occam's razor (the simplest answer is the correct one) may not apply here.

On global splits

I think the US and many other US allies have their interest. Similarly BRICS countries have their interest.

On Maduro’s policies

Maduro’s economic policies are bad as it's not been reformed, nor diversified. Not because socialist policies are bad. Some of the richest countries in the world are socialist democrats. The unreformed ones are the poorest. But many are triggered by the word socialist without understanding the broad spectrum of it.

On dictatorship

This can exist on both sides of the spectrum (left and right) and the people have had enough of a 20 year party ruling. If you have benevolent dictator like Lee Kuan Yew, Bukele than that's another story but most dictators are corrupt, oppress the country and destroy it.

US influence on change in regime

Well this is a known case that the US has had its hand in many countries over the last several decades. In fact the US imposed sanction on Venenzuela a few years ago to force a change in regime.

On fraud election

Not surprising - i’m from a country that have witnessed it myself first hand. It happens. Whether its was fraud or not i do not know but it can happen

Regardless, it boils down to 2 things :

1. What do people want ?

If the Venezuelans want a change in regime on a large volume, then that’s by definition democracy. Whether a change in regime will be better for the country idk but it's what the people want. Its easy to say they are influenced. But they live through it day in day out for 20 years

How can we prevent global political splits in the future ?

Bitcoin as global currency - its a long journey but this will slowly prevent currency wars

Another thing to really consider is how to prevent algo influence on the lives of these people ?

And this is where Nostr as social platform becomes incredibly important. The pH of people will more accurate without external influence
