Not everyone agrees with this world-wide division of powers and authorities. Yes, this prevents evil men from having a monopoly of power here on earth, and often pits evil men against evil men in their quests for unrestricted power. Sometimes these battles are truly terrifying. David comments,

“Yahweh brings the counsel of the nations to nothing.
He makes the thoughts of the peoples to be of no effect.”
Psa 33:10

By such means God continually restricts the reach and grasp of evil men. Satan though intends to offer the ultimate solution to the divisions of worldly powers.

Satan intends to offer a substitute “god,” another
“god”/man whom ALL have to worship.

If ALL men HAD TO worship just ONE MAN, that would provide the foundation for unifying all of ideas under that ONE MAN. (See the post on “Religious Ideas are the Foundation of ALL Politics.) That would provide a sure framework to end all of the diversity in religion, and that is the root of our political diversity. It would provide a basis for world-wide unity. Paul says of this “god”/man,

“he who opposes and exalts himself against all that is called God or that is worshiped; so that he sits as God in the temple of God, setting himself up as God.”
2Thes 2:4

He is called “the beast” in Revelation. He is talked about under several names and phrases in both the Old and the New Testaments. The “mystery of lawlessness” occult (hidden) religion that will eventually produce this world ruler, “already works” in the first century, 2Thes 2:7. God will at the last allow him a short reign of three and a half years (for a time, and times, and half a time).

“… Authority to make war for forty-two months was given to him. ”
Rev 13:5

Many think of this as hard times for the church

And it will be. However God will once more provide for His faithful ones in “the wilderness.” You might think of this as the second (and final) exodus out of this world.

“Two wings of the great eagle were given to the woman, that she might fly into the wilderness to her place, so that she might be nourished for a time, and times, and half a time, from the face of the serpent.”
Rev 12.10

Even so, this is also times of extreme stress
for the entire world.

This man will come with powerful Satanic signs and wonders (2Thes 2:9), including some sort of his being raised from the dead.

“One of his heads looked like it had been wounded fatally. His fatal wound was healed, and the whole earth marveled at the beast.”
Rev 13:3

No one will be able to buy or sell or trade anything unless they accept this man as “god.” And if you worship him, you will perish forever, Rev 13:8, 17.

This is not some sort of premillenial invention. This is Scripture and it clearly has NOT happened yet. All but a few faithful will worship him, very near the end of the age.
