There is nothing crazy about noticing the world is (to put it mildly) in danger.
Stockpiles of nukes in USA, Russia and some other nations alone mean the world is in danger.
For years some secular scientist have maintained their "doomsday clock" ....
Timeline
Many, even most, see and sense the rising tension of colliding cultures .... notably rising Islam influence in Europe and USA ...
Islamic aggression against Myanamar (seen in light of CENTURIES of Muslim aggression against all non-Muslims,
most pertinent being centuries of Muslim aggression against the Hindus and Buddhist of India, Afghanistan, Bangladesh, Malaysia and Thailand.
All the modern Islamic aggression being supported by the pope (kingpin of Western Civilization (formerly called "Christendom") for centuries).
Add to that the world financial system situation ... which many have likened to a flimsy house of cards that is bound to crash ... just don't know exactly when
In light of many millions of religious people (big percent on internet) it's no wonder that regularly a FEW think this or that day will be THE very special day of doom
Of course, one of these days a few of them will be right ! Regarding date setting, I learned my lesson the hard way.
But I agree that the "sovereign" nations are going down and the current world order is coming to an end sooner rather than later.
Like watching a volcano and knowing it's gonna blow ... but now knowing exactly when.
