Isaiah 14:4, Isaiah called the antichrist by the name "king of Babylon", because he will make the rebuilt city of Babylon one of his capitals during his short reign.
Both Isaiah and Revelation show that the city of Babylon will be rebuilt and finally destroyed by fire from heaven from God during the 'Great Day of the Lord.'
The Iraqi government under Saddam Hussein spent hundreds of millions of dollars rebuilding the city. It will be burned when the antichrist is destroyed by Jesus' return.
