This is one of the many Capitalist PROPAGANDA. Real truth is that both WWI and WWII and every other war thereafter, was in fact created by Capitalists, mainly from US and UK. If you count all the deaths caused by these wars, you end up with more than 100 million deaths, and the rubbish 100 million figure that Capitalists say was caused by Communism, will start to see like a fairytale, which is what it is.... complete BULLSHIT, same as everything else narrated by Capitalists. Capitalists can't even define their own fucked up exploitative economic system for what it really is, instead they use nice outcomes of Capitalism to define Capitalism itself, which is just pure horse shit, and you people were fed this horse shit all your lives so you don't know any better and can't see when you have been fed horse shit.
