If you mean JW`s and their God /King ruled the earth as one Government for the next thousand years the human race would become extint ,
Think about all the directions given over the years by JW`s and we would be living back before the stone age.had even begun.
It could not be anything but a hell on earth ,no modern technology ,no higher education ,none of the benefits that mankind has received would be achieved such as Medical, scientific,Dentistry ,numerous health benefits , under a theocratic rule in the future.
In the Old Testament when Theocratic Rule was reigning over Gods Chosen people and Jehovah was blessing them ,these facts still remained .
Leprosy still existed in the land ,Why ?
Wars were conducted under a theocracy and still Gods people were slain even when Jehovah blessed them as a nation.
Slavery was condoned ,and women were treated as second class citizens to be exploited
JW women shouldnt be expected to be treated much better than Muslim are women today
