Recent world history

If you look at modern history and politics the last 70 years it becomes more and more plausible that it’s all a consequence of multiple and increasingly complicated time-travel events. They probably started as misguided attempts to correct an initial mistake in altering the original timeline, but then the error cascade escalated beyond control and the time-travelers panicked when their plot got too messy to understand. Either that or we have a world in disarray because of incompetence and chance.
