Rev. 20:3, 8, states that "nations" will survive the calamaties of the end time, continuing into the millennial kingdom in their natural bodies. A remnant of them, Zech. 14:16 identifies them the remnant "of all the nations" that are "left," i.e., who survive the end time, Armageddon being singled out, "the ones who came against Jerusalem."

BTW, Rev. 20:8 is speaking of the period at the end of the Millennial reign, not after the Tribulation...But how did they get there...You figure that after Armageddon God is going to let a bunch of heathens move into the Millennium???
