An effective thesis has a definable, arguable claim. "While cultural forces contributed to the collapse of communism in Eastern Europe, the disintegration of economies played the key role in driving its decline" is an effective thesis sentence that "telegraphs," so that the reader expects the essay to have a section about cultural forces and another about the disintegration of economies. This thesis makes a definite, arguable claim: that the disintegration of economies played a more important role than cultural forces in defeating communism in Eastern Europe. The reader would react to this statement by thinking, "Perhaps what the author says is true, but I am not convinced. I want to read further to see how the author argues this claim."
I know the video that you are talking about, but be aware that Trump did not actually make that video! It was created by an indie producer named Mike Diva. So if you want to write a thesis statement around this video, you’ll want to understand it’s purpose according to the creator. Diva writes about his video, “Trump is turned into the ultimate teen idol, dictator, and action hero, all rolled into one. He seig heils in front of a swastika and destroys the world, but he creates an amazing spectacle in the process. And the video seems to be saying that that’s all the media really care about.”
