On Tyranny by Timothy Snyder

Modern tyranny is terror management. When the terrorist attack comes, remember that authoritarians exploit such events in order to consolidate power. The sudden disaster that requires the end of checks and balances, the dissolution of opposition parties, the suspension of freedom of expression, the right to a fair trial, and so on, is the oldest trick in the Hitlerian book. Do not fall for it.

THE REICHSTAG FIRE was the moment when Hitler's government, which came to power mainly through democratic means, became the menacingly permanent Nazi regime. It is the archetype of terror management.
