God said He will bring a sword against the invaders, as well as fire, etc. & that every man's sword in that armywill be against his brother's, meaning that the coalition will disintegrate in mid-invasion.
here are GOD'S words in Eze. 38:
21 I will call for a sword against Gog throughout all My mountains,” says the Lord God. “Every man’s sword will be against his brother. 22 And I will bring him to judgment with pestilence and bloodshed; I will rain down on him, on his troops, and on the many peoples who are with him, flooding rain, great hailstones, fire, and brimstone.
So, at least one great nation, likely several, will come against Gog's army, as well as the coalition's falling apart, but the event which will destroy 5/6 of that army will be GOD'S rain of destruction on it, most likely to be shown live via satellite TV.(Hello, CNN ?) Seems much of the world, especially the Israelis, will realize this is GOD'S work, & that JESUS is Messiah. (Naturally, there'll be some Jews who'll say they were under God's protection no matter what, & say they were ENTITLED to be rescued cuz they worshipped Him correctly!)
I believe the 'beast' will be on his way to his full power then. He will most likely broker the deal that causes Israel to disarm, along with her enemies, making the beast to seemtabee a super-genius in the world's eyes. After the destruction of the invading army, the beast will move quickly to take over the nations that conducted the invasion, now that their military won't be strong enough to begin to stop him.
