Gonzalo Lira, the real name of "Coach Red Pill", is a talented Chilenian/American artist and certainly an intelligent man. However, one should always beware of anyone who claims they can predict the future. Simply because the future is too complicated to predict in normal circumstances, too many variables. So let's examine what he's claiming in that video.
1) Leftist democracy is on the rise in the West - Well, yes, but this has been the case since 1878 when Bismarck himself enacted socialist reforms in Germany. That was the beginning of state socialism. Post WWII and the 70s in particular literally almost all western democracies have in fact become left-wing social democracies. There was some slight resistance in the US, but with Obama we have confirmation that this too has weakened. The left-wing social democracy is the de-facto state of democracy for some time.
2) Leftist democracy is turning totalitarian - Whilst the current emergency corona measures around the world do have totalitarian overtones, and Lira makes much of that, it is inconceivable that emergency powers, clearly limited in scope and time by law, will not be given up when the fourth and final wave of the virus has disappeared. One should not compare the Bolsheviks, who were fighting a real aristocratic enemy with fanaticism, due to a clear ideology, with the disaparate currents trending western democracies who are using emergency powers to enact policies, admittedly false in many cases, but which the political class thinks are necessary. Indeed we already saw in the UK, and then the US, that once the virus threat is diminished restrictions are quickly lifted. The same will happen in Australia, Lira is not convincing here.
3) War with China - He is predicting war with China is imminent if not this year "within days" then next year. However, we have seen that even the top US military leadership in the form of Mark Milley is going out of its way to tell China that the US will not attack in top level talks. Trump himself confirmed he had no intention to attack China. Will Xi Jinping risk going to a war which, even if he wins, could destroy the Chinese economy and certainly risk nuclear war with the US? Over Taiwan? You never know, but this seems very unlikely. Particularly since China can grow its economy peacefully, build its silk road and establish hegemony in the long term. It is far from clear there will be a war with China.
I would not base my life decisions on a Youtube video made by Gonzalo Lira, who clearly has no top level insights or secret information, but instead bases his ideas on the flavour of the moment, coronavirus policies and tensions with China. What if you move to Cambodia and find out China is going to war? Doesn't sound like you'd be in a better place.
