@sawas and @Wings Like Eagles have said what I was thinking when I saw your question.I'm sorry for my ignorance but if the Magog war starts before the tribulation what is the war (second seal) during the first half of the tribulation? Could that be a world (nuclear) war?
The wars of the Antichrist seem to happen on multiple points during the Trib. We know according to Daniel he eliminates 3 of the 10 kings or rulers and becomes the 8th in the midst. That has often made me think this might be regional wars against the areas of those kings. I've often thought that shortly after he appears (Seal 1) he does something to cause the war described in Seal 2 I've thought he maybe does his number on the 3 kings out of the 10 at that point.
My logic there holds only if the 10 kings appear first before the AC does, so you are free to ignore my random thought -- it's not a crucial point.
Finally even if the AC gets it all done via assassination and intrigue, wars happen on his 7 year watch and by the end of the Trib the battle of Armageddon takes place which is another of his wars-- it's the culmination of his efforts since the mid point of the Trib to exterminate the Jews.
This battle described in Ezek 38 has never yet happened, so it's yet future to our point of view. It can't be the same as Armageddon for reasons that Jack Kelley describes and we've covered right at the first page of this thread, so it looks like multiple serious wars happen after Ezek 38 even if the Jews have a period of peace in the first little while after that. (which allows the burning of weapons)
