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 ?
For my knowledge because United States is most influential country. All the things in the world that we used is came from USA. All the expensive things came from USA, that's why everyone are dreaming to live in United States.
