I wish it wasn't impossible, but it's in our nature to control others dating all the way back to the beginning of our existence. Not everyone can agree on the same things and individuality isn't held very high when it comes to all countries.
That won't happen until Christ returns. ======================================For unto us a child is born, unto us a son is given: and the government shall be upon his shoulder: and his name shall be called Wonderful, Counsellor, The mighty God, The everlasting Father,(((( The Prince of Peace. ))))Of the increase of his government and (((peace )))there shall be no end, upon the throne of David, and upon his kingdom, to order it, and to establish it with judgment and with justice from henceforth even for ever. The zeal of the Lord of hosts will perform this. (Isaiah 9:6, 7 KJV)
