Ezekiel 38: Israel against a coalition headed by God

I suppose that when Ezekiel 38 was written, Jerusalem was destroyed and there was no Israel. Ezekiel prophecies many times that Israel will rise again (ex: Ezekiel 37). Here, besides the formation of the new Israel, we read about a coalition of many nations against Israel:

1-6 God’s Message came to me: “Son of man, confront Gog from the country of Magog, head of Meshech and Tubal. Prophesy against him. Say, ‘God, the Master, says: Be warned, Gog. I am against you, head of Meshech and Tubal. I’m going to turn you around, put hooks in your jaws, and drag you off with your whole army, your horses and riders in full armor—all those shields and bucklers and swords—fighting men armed to the teeth! Persia and Cush and Put will be in the ranks, also well-armed, as will Gomer and its army and Beth-togarmah out of the north with its army. Many nations will be with you!

The Lord himself will defend Israel against this coalition:

17-22 “‘A Message of God, the Master: Years ago when I spoke through my servants, the prophets of Israel, wasn’t it you I was talking about? Year after year they prophesied that I would bring you against them. And when the day comes, Gog, you will attack that land of Israel. Decree of God, the Master. My raging anger will erupt. Fueled by blazing jealousy, I tell you that then there will be an earthquake that rocks the land of Israel. Fish and birds and wild animals—even ants and beetles!—and every human being will tremble and shake before me. Mountains will disintegrate, terraces will crumble. I’ll order all-out war against you, Gog—Decree of God, the Master—Gog killing Gog on all the mountains of Israel. I’ll deluge Gog with judgment: disease and massacre, torrential rain and hail, volcanic lava pouring down on you and your mobs of troops and people.
