Every “rod of iron” text you cite describes judgment, not administration, and every passage you use to prove a temporary earthly kingdom actually proves the opposite:
Psalm 2:9 is God warning the nations that Messiah will shatter them, not govern them;
Revelation 2:27 says the same — “rule with a rod of iron” means break to pieces, not “manage survivors”;
Revelation 12:5 shows the child caught up to God’s throne, meaning the rod‑of‑iron authority is exercised from heaven, not from an earthly throne;
Revelation 19:15 is the final destruction of the nations, not the beginning of a millennial government; and
Zechariah 14:9 says the Lord becomes king over all the earth after cosmic collapse, which matches the day of the Lord destruction (2 Pet 3:10–13), not a 1,000‑year intermission.
The world‑system driving your interpretation is the earth‑kingdom assumption — the belief that nations survive Christ’s appearing long enough for Him to run a transitional government, even though every rod‑of‑iron text says He destroys them, not supervises them.
Revelation’s sequence is judgment → destruction → marriage supper → new creation, not “judgment → millennium → new creation.” Nothing in your verses teaches a temporary earthly kingdom; every one teaches final wrath, final victory, and final new creation
