Chances are extremely high of tens or hundreds of millions dying of PanFaWar in the next several years.
Notice they blame Putin for the lot.
The reality is that this elective war creates additive stresses that can, and likely will, lead to the toppling of governments. Mass migrations. Possibly a toppling of various State governments in the United States, and even of the Federal Government. And all this is without the use of a single WMD other than hunger and other forms of silent attack such as fake ‘vaccines.’
That said, chances that nuclear weapons will be employed has never been higher other than just before bombs detonated over Japan. We are toe-to-toe with World War III. Even short of nuclear weapons, conditions are growing to create massive starvations that would make the term Biblical entirely appropriate.
Consequences of failure to prepare may be final.
Prediction: By 2025, or even 2024, the human population on earth will decrease.
