“More to the point, has anyone looked at the terrain and distance between China and Israel? The logistics of a movement of that size army across that terrain is quite beyond what is possible”
Chinese armies (mongol to be exact) have gone further in times past and all they had was horses. All it takes is the will and the power. God says it will happen. Will it be the Chinese, nobody really knows.
The Mongols went all the way to Germany.
But there weren’t 200M of them. More like 20,000.
The Mongols did, however, manage to kill roughly 10% of the world’s population. No other group has ever come close to that feat.
They also were far more efficient killers than the Nazis. The maximum output for a 24-hour day at Auschwitz was 24,000. The Mongols routinely killed several times that many people in a hour or so. All done with edged weapons.
Which pretty much blows a hole in the idea that mass killing requires technology.
