The world is currently witnessing such narrow-minded problems in the middle-east, between Israel and Palestine, the far-east and many other regions of the world. As the name suggests, Superman is superhuman. If Superman ruled this world, there would not be any boundaries between nations and even the concept of sovereign nations will dissolve in the vast sea of human compassion, love and brotherhood. The Planet earth as a single nation would be a real paradise. .
If superman ruled our planet, the entire power would be concentrated on him and decisions would be made with ease. In our world, the authorities are bound by numerous factors that repel them from executing reforms that are beneficial for the common man. Superman will have absolute power, and there will not be any need for any consultations. Superman is omnipotent; hence he can execute his decisions in the best way possible. .
Superman's step-parents brought him up feeding him with high moral values. Hence as seen in many of the stories, his reign will be a golden age for women in trauma, suffering children, and old people. Superman demonstrates extreme aggression to wife beaters, gangsters and profiteers. The superman after the 1940s is a character which is much softer and gentle, even to the enemies. The new editor Whitney Ellsworth made his character more humane and after this change, superman stopped killing opponents. However, the attitude of Superman towards the elements of threat to the world is extreme.
Terrorism is the biggest threat to the world now. Superman's reign will ensure the wiping out of terrorist activities and killing of innocent people around the world. He is omnipotent and has the capability to fly fast. His physical presence will be at all the places where justice is denied. His extrasensory perception capabilities will help to foresee plans of terrorist groups and to defeat their plans. The dark forces operating in different parts of the world will have a real bad time when Superman rules the earth.
