Is it true that the idea of manifest destiny was that America is certain to become the most powerful country in the world

Answer 1

The concept of manifest destiny was the belief that the expansion of the United States across North America was inevitable and justified. It was not specifically about becoming the most powerful country in the world, but rather about the right and duty of the United States to expand its territory and spread its political and economic systems throughout the continent. This belief did contribute to America's eventual rise as a global power, but it was not the sole focus of the idea of manifest destiny.
