If Nostradamus' predictions are correct, we are in the right time for the next major tyrant to show his face. He predicted a long global war that modern Nostradamus experts believe would arrive "in the next few years .... certainly this century" (as reported via 7News). 

Nostradamus predictions continue until the year 3797, so this is, perhaps, a sign of good news -– the world as we know it will likely not end in 2023 (per Sunday Post). But Nostradamus experts do agree that 2023 is meant to be a year of deep changes and disasters. A major war is a constant in his predictions for 2023, and so are mentions of the destruction of a large empire (which could be interpreted as China or, even more timely, Russia) and the loss of a large number of people in Europe (as reported via Yearly Horoscope). 

In addition to a global war, Nostradamus also predicts financial chaos, political instability, poverty, a new Pope who will spell disaster for the church, and civil chaos and immigration problems for 2023. While many of these predictions are vague enough to apply to many situations and countries, it's very clear that at least the war prophecy is very much related to Europe -– which makes it particularly terrifying if you're a believer.
