So much of America's power comes from its size: it is one the largest countries on Earth by population and area, and is rich in natural resources and human capital. It is also in many ways an island nation; because it faces no major threats on its borders, it is freer to project power globally.
The United States had as its first reaction the freezing of the accounts of the Japanese in America, the suspension of commercial activities and the shipment of supplies, as England did, this would block the entry of money and oil from abroad and economically suffocate the empire of Japan that would scarcely have 3 years of supply, if it did not enter into war, this infuriated the Japanese who would then attack Pearl Harbor and cause the sending of American troops to South Vietnam, participating in a war, that at first, it didn´t correspond to them.
The events that led to the division of British India into India and Pakistan was a method the British had to secure how independence would take place. The British government had a system of political control of “divide and rule” and because of that, this strategy was perfect.
Muslims were 25% of British India’s population, therefore a religious minority. They were afraid of losing protection as the independence of India got closer.
With the approach of WWII, things got even worse, since the British took India into the war without consultation of the population or the legislative, this caused even more pressure for independence and the creation of a separate state.
The separation between India and Pakistan caused riots, mass casualties, a wave of migration - Muslims headed towards Pakistan and Hindus and Sikhs headed into India -, and a death toll of 2 million people.
