Beware the Ides of March

"They are come, but not yet gone."

Thus spoke the soothsayer to Caesar when the dictator perpetuus said to the soothsayer that the Ides of March had come and he was still alive.

Dictator perpetuus has an overly confident ring to it much like eintausendjähriges Reich. 

Some history here.
