Complexity is about structure, or connections that are operationally reproduced (sustained) in time. Systems connect elements to establish structures.
At its core, the Donald Trump’s campaign and similar brands of reactionary, neo-nationalist politics around the world are all about the denial of complexity. It is an effort to disconnect elements that systems have established over time.
Trump and his followers want to deny the complexity of things like gender and race, the complexity of the global economy and global politics and, probably most dangerously, the complexity of the global climate–the connections between fossil fuels and climate change. Trump says he wants the United States to be “energy independent,” and tells people that his goal can be achieved by burning every bit of fossil fuel that can be found within the territory of the United States. He wants to cancel or back out of every international climate change agreement (along with trade agreements). He wants to build a wall around the United States and pretend that nothing else exists and that there is no such thing as a system. But interestingly, he exempts Canada from this policy because he wants to build the Keystone XL Pipeline. Similarly, he says he is willing to grant exceptions to his no-Muslim policy by allowing individuals like the Mayor of London, Sadiq Khan, to enter the country.
Trump will say anything to stay in the news and to become president–and the only reason he wants to be president is so that he can stay in the news every day.
