She was a F*cking prophet:

On politicians in America and the culture of lies as nomality
-If everybody always lies to you, the consequence is not that you believe the lies, but, rather, that nobody believes anything any longer.
And the people that no longer can believe anything cannot make up its mind.
It is deprived not only of its capacity to act, but also of its capacity to think and to judge.
And with such a people, you can then do what you please. https://www.nybooks.com/articles/1978/10/26/hannah-arendt-from-an-interview/
