The answer to that question is yes. That moment is closer than what you might think, from a secular standpoint you can research the L.O.S.T treaty in which most nations have agreed to a world government where the United Nations would rule, they would control all the bodies of water on the earth and have power for taxation as well as establishing boundaries.
From a biblical standpoint it was foretold about 2000 years ago that this would take place in the book of Revelation (or Apocalypse) Regarding events that would take place in the last days Revelation 16:14 it states "They are in fact, expressions inspired by demons and they perform signs, and they go out to the kings of the entire inhabited earth, to gather them together to the war of the great day of God the Almighty." You notice here that Satan and his demons play a role in uniting the nations in opposition to God's kingdom. This makes sense and harmonizes with 1John 5:19 - "The whole world is lying in the power of the wicked one." These are just some examples of scriptures that support this.
