But Revelation 16:14 indicates that “the kings of the entire inhabited earth” mobilize a united front at “the war of the great day of God the Almighty.”

Therefore, Armageddon is not man’s war. It is God’s war. Armageddon will find all earthly nations united in battling ‘the armies of heaven’ under the military command of the “King of kings and Lord of lords,” Christ Jesus. He is the rightful ruler of the world because God also “subjected all things under his [Christ’s] feet.”​—Revelation 19:14, 16; Ephesians 1:22.

Who are gathered to Armageddon and why? Revelation 16:14 answers: “The kings of the entire inhabited earth” muster “to the war of the great day of God the Almighty.”

Those answers raise a host of other questions. With whom do “the kings” battle, and over what issue? Where will they fight? Will they use nuclear weapons? Can the war be prevented? Really, what is Armageddon?
