An alien armada made themselves known to the world. They asked to meet all the world leaders. So, every single leader of every single nation gathered at the UN building in New York and met a delegation of alien visitors.
"For 10,000 years your race has been an experimental project of ours. We have been watching and monitoring your world progress. We have been unimpressed with your efforts. Your world is chaotic with sparodic wars. We are very disappointed. Therefore, we've decided to terminate the project and your world."
The leaders of the world pleaded in unison for a second chance. "We'll clean up our act. We will do better!"
"Ok" said the aliens, "We will return in 1 week."
So the leaders got together, settled their difference, abolished all geographic and political boundaries, allocated and evenly distributed the wealth to all nations. There is no longer east and west, poor and rich coountries, they abolished religion, and all races are given equal rights.
A week passed and the aliens returned. They leaders congregated and presented to the aliens their achievement. "What we cannot do in thousands of years, we've achieved in 1 week. This world is finally united and finally at peace."
The alien then replied, "You've misunderstood. We've created this world and bred your species to be a warrior race for our army. Your efforts are in vain and a failure to us. You will be terminated!"
