The US has 7200 nuclear weapons and China has 260 according to http://armedforces.eu/compare/countryUSAvs_China. This means that the US has the military advantage.

Armed forces of the Russian federation ranked 5th out of 1,013,000 people.

I think that Russia will be the next super power. The president of Russia is head of the state and of a multi-party system with executive power exercised by their government headed by the Prime Minister appointed by the president with parliament's approval. Russia won the economy. Means how much money a country has. They are leaders in producing oil and natural gas. Also a top export of steel and primary aluminium.

I agree with you. We should have given Japan a warning and not have killed as many people. Instead, the U.S. should have left them alone but Japan shouldn't have dropped the small bomb.

The U.S has bigger bombs that can kill more people. Japan was not right to cross are side of the world but Japan only hurt our army the U.S hurt their whole city.

Truman believed their another attack world cause about a million US deaths as well as more japanese deaths.
