I agree with the military winner with the USA and how they have a higher budget

Economy: The US will be the superpower of the 21st century. One reason the US will be the superpower is because the economy of the country is very good. Only until recently, China has beat the US economy-wise. Second, people listen to the US. For example, when Hurricane Harvey and Irma hit this summer, many people from across the globe donated to both the Hurricane Harvey Fund and the Hurricane Irma Fund, and raised a crazy 44 million dollars . And Lastly, we have a size of population. In America, there is 323 million people as of 2016.

Political: The United States is part of all of the huge Allied groups like NATO and the UN Security Council compared to China only being part of one huge Alliance, the UN Security Council. The United States also produces the top watched movies and TV shows in the world which has lots of influence on other countries. Although China has the most exports in the world, the United States is not far behind.

Military: the US has the better military for several reasons. Yes China may have more personal, but the USA has a total of around 14 Thousand total aircraft space. China has close to 3 thousand total aircraft space. The USA also has more aircraft carriers as well.

That is why the USA will be the superpower of the world

I disagree because they killed the people in Hiroshima and Nagasaki with bombs so the war could end Sacrifice the few to save the many for both sides.

Yes, it was. The US was, like the rest of the world, soldiering on towards the end of a dark period of human history that had seen the single most costly conflict in history, and they chose to adopt a stance that seemed to limit the amount of casualties in the war, by significantly shortening it with the use of atomic weapons. http://www.historyextra.com/feature/second-world-war/was-us-justified-dropping-atomic-bombs-hiroshima-and-nagasaki-during-second

The USA should not be worried about North Korea. First North Korea's missile program is way back in the 50s. 2ND the missile can not even hit the main land USA. 3rd North Korea will not nuke us if we do not threaten them. https://www.rt.com/

Veto is good for the un because if something is bad you can veto it they could all agree to bombing north korea and if you didn't want to start war then you could veto it.
