Considering that the video was uploaded by someone called "Everything is a rich man's trick," I would recommend not wasting your time. To start, anyone making such sweeping historical claims (and in their profile name) is guaranteed to either be an amateur in history at best, or a conspiracy theorist at worst. WWI, 9/11 and JFK are all favourite areas of conspiracy theories, usually arguing that some plutocratic elite fomented historical events for profit. I can speak to the case of WWI and say that this is demonstrably false. Businessmen and capitalists were not represented in any of the leadership circles in Berlin, Vienna, St. Petersburg, Paris or London. Moreover, many wealthy businessmen such as Carnegie, Bloch, Nobel, and Ford had supported pacifist, anti-war initiatives before WWI, and in Ford's case during WWI. Bloch actually wrote a multivolume work called "Is War Now Impossible," arguing in the affirmative, and his work was a driving force behind the Hague Conventions, the third of which was scheduled for 1914 and then 1915, but was interrupted by the war. [Richard Hamilton] (https://www.youtube.com/watch?v=4e_RfFzyris) has written on the subject, and I've posted his lecture on the subject.

TL;DR: Ignore it

I clicked to a random part of the video and it started talking about how the Illuminati picked Hitler, at which point I immediately quit the video to preserve my sanity.
