Yet Revelation 20 says the war of Gog/Magog occurs after the thousand year reign of Christ. A bit of a problem for premillennialism.
Ezekiel 38 & 39 seems to be about Satan and nations declaring war on Israel whereas Rev. 20 is about Satan and nations declaring war on God.
A variety of opinions on why Gog/Magog is mentioned in Rev. 20.
What are Gog and Magog?

Exactly. Christ has not returned yet. His millennial kingdom has not been set up and concluded.
The battle between Gog and Magog is at least 1003.5 years in the future.
