America has been setting up a democracy in Iraq which is ancient Babylon.

The Fourth Empire is Rome.

The book of Revelation tells of two more empires, which make a total of eight great world empires controlled by Satan that oppress the Jews.
Even though there may be good reasons to create a global government for economic and peaceful purposes, the force behind one world government is Satanic.
The Second Coming of Jesus Christ is referred to in Revelation chapter 19:19.

We read about how the Antichrist or the "beast and the kings of the earth and their armies gathered to make war against Him who sat on the horse and against His army."

The world will try to fight Jesus at His return because they are in rebellion from Him.
"For the mystery of lawlessness is already at work: only He who now restraints will do so until He is taken out of the way."
2 Thessalonians 2:7

The "mystery lawlessness" is the power of sin and evil that is leading the human race to create a global government that will be headed by the Antichrist.
The current push for a one world government and globalism is driven by men's impulse to rebel against God.

It's a repeat of what happened at the Tower of Babel under the leader Nimrod.

The human race is in rebellion from God and they are seeking to create a world without God.
