I must warn you that this is a very lengthy post (you might want to start at the eighth paragraph) and it is only one segment, however I felt that the speaker's general overview of the main currents of geopolitical history since, and including, the Nazi era offered so much that was valid and insightful in this last capitalist stage of imperialism. Here is only one sample of his perspective:
[Capitalism] seems able to produce only or mainly catastrophes. It is true that many people around the globe believe global socialism is unrealistic, that talk about it is, at best, a romantic exercise. But in reality, if there is something totally unrealistic and completely utopian is to hope that Humanity will be able to survive this century without inventing a radical new and human order. This is today much more clear than it was at the time Marx and Engels were writing their Communist Manifesto or Rosa Luxembourg was formulating her dilemma “Socialism or Barbarism”. And it is true for the whole world, not only for the Global South and West, but also for China, in spite of its tremendous achievements. It has become long ago impossible to separate the destiny of any state, country, nation, or continent, even of the strongest ones, from the destiny of the world.
