In the past the entire planet was involved in wars: Ancient Rome, Mayans, Aztecs and Incas, Ancient China, Ancient India etc. World War II and Cold War. Today, the planet in general, is more globalized. There are some localized wars. The tendency in the future is to have less and less wars. Governments spend billions of dollars on armaments. The "warlike" companies will not exist in the future, there will be no more wars in the future. Does it seem utopia? The law of probability says that it is possible.
