Not every thing old is new again but there are some

ICE is the new deportation Gestapo (papers please)
Free Speech is the enemy of the people is an old dictator lie
FOX-Sinclair media is the new Goebbels
Nazis claimed to be good loyal people is old
Purges are occurring in the Government and have decimated depts.
Attempt to control the Justice Department is like the old Hitler Courts
There is a new personality cult called Trumpism
This list can be extensive and I haven't even mentioned Bannon yet

We are fortunate Crises are only man made so far (except for hurricane) and have spared us.
