Take responsibility for the face of the world. The symbols of today enable the reality of tomorrow. Notice the swastikas and other signs of hate. Do not look away, and do not get used to them. Remove them yourself and set an example for others to do so.
In his Substack newsletter, Snyder encourages people to start organizing now (2024) in order to win both local and national elections.[15] He notes that On Tyranny was written in a defensive mode and that if its lessons are learned and implemented now things could get much better in 2025 for those who want to maintain democracy and the rule of law in the United States.[15] Snyder has noted that while Trump did not succeed in overturning the 2020 election, it was practice for a successful coup and his supporters will be better prepared for 2024.[16] He also notes that in 2020 important individuals and institutions were aware Trump might not want to peacefully transfer power if he lost the elections and that they prepared to make sure lawful transfer did occur.[16]
