No one side would any nuclear battle.
Since nuclear fallout is carried on the wind and within water, the entire world would lose.

It's unlikely but if it did happen it would be very
Here are the points why that Russia would could beat America in a Nuclear Battle/War
However here is the more positive side why America could win a Nuclear Battle
However, neither could win due to if a Nuclear Battle/War did Happen, the amount of radiation would practically end live.
However, like I said before, It's very unlikely that it would happen due to both countries agree to reduce the numbers of Nuclear Weapons and agree to be friendly/neutral with each other. Theres like 1:100 thousand chance of a Nuclear War happening unless one or both countries has a government like Adolf Hitler or Joseph Stalin.
Russia. They have way more nukes then China.
Russia has nuclear weapons and a modern army. Japan has put the military aside since World War II.
USA will win because of advanced technology and mor nuclear weapons along with better money and more experience
No one. The US, Russia, and China each have sufficient nuclear weapons to lay waste to the entire globe.
no one because the nuclear nations would destroy each other Edit: (My opinion). I do not think that is true; Mainly because I am leaning on Russia winning a Nuclear war due to its far more superior number in nuclear power (11,00-15,000 estimated) than the U.S.A's (8,000-10,000 estimated). Also Russia is too big of a land to destroy and not to forget Russia has the most powerfull Nuclear Warhead: The Tolop-M. Also If Russia does not win. Nations wouldn't destroy each other and end it all. There would ALWAYS be survivors to tell the truth and their is ALWAYS a country that wins, and if there were a Nuclear War. That country would most probably be Russia. ^^^^ This guy is a total ideot. If there was a nuclear war, EVERYONE would loose. And do some research. The Tsar Bomb is the largest. If there was a nuclear war then russia and the usa would be the mostlikely targets due to their size. And i doubt it would be all vs all. The USA, UK, France, India Vs North Korea, China, Pakistan and Russia could be an example. Besides, nuclear wars arent going to happen. If you nuke someone you are basically nuking yourself.
It is likely that US might win the war. Russia could defeat both India and China together, but they would get a lot of their soldiers lost in the battle. US has much better weapons and better, trained soldiers than Russia, making it more powerful.
Nobody- you cannot win a nuclear war. You may want to watch the film 'Threads' on YouTube for a good simulation of what a Nuclear war would do.
Russia has a much larger military. Russia.
Russia
An orca would win the battle!
In a non-nuclear war, The United States has the advantage of superior military power, and technology, and having Alaska as a staging ground. While Russia, has no advantages. If Russia had invaded, then they would have to march through Canada first before being able to reach Mainland USA, and the Canadians wouldn't put up with that. While if the US invaded Russia, The Russians have the advantage of the Russian winter, knowing their battlefields, and having almost no route from Vladivostok, to Moscow. In a Nuclear war, Neither, both countries would be so damaged from nuclear warfare, that they would both be nothing but wastelands. But in a non-nuclear war, it all comes down to the tactics used.
The US would never fight a conventional war with China or Russia, but might support a country that did (as with Afghanistan from 1979 to 1989). Russia has a much larger conventional army, and China an even larger one. Any armed conflict would likely lead to a nuclear exchange, either limited or total. Russia has parity with the US in nuclear weapons, while China is still a distant 3rd.
