Terrorism went from "kill one person to scare millions" to "stir shit up to cripple the adversary with the costs of prevention".
I remember, after the Snowden leaks, when anyone warned that governments could use the patriot act and the various other "intelligence" power grabs to destroy democracy and implement totalitarian dictatorship, they would be deemed insane conspiracy theorists. The hilarious part is most of them (including me) were warning about a distant future... yet it barely took a decade for America to collapse into fascist populism, declare ANTI-FAscists the real terrorists, and turn the surveillance apparatus against them.
