After the second world war, US became the most powerful country in the modern world. With nuclear weapons, space explore, big scientific progress. But what can be the reason for this huge power ? Military power ? Strong economy ? Diversity in society ? Or something else ?
Yes, maybe they were. I dont know how they became one of the powerful countries in the world. Maybe, because they take all the great inventors and scientists from their enemy,(Germany Adolph Hitler) that is why they were the first to developed the first nuclear weapons and the first to walk in the moon. They really had a strong economy, way back 4 decades ago. Many third world countries borrowed money from them to develop their countries..where it came from. I honestly dont know. Maybe they have oil. Or they control the oil in the middle east. But, today. I believe China and Russia are the 2 most powerful countries in the world.
U.S.A are still recovering from their economic crisis in 2018.
