Probably China. There are many discussions about this, look online.
Russia. They have way more nukes then China.
For North Vietnam to win the war; which they did.
No one. The US, Russia, and China each have sufficient nuclear weapons to lay waste to the entire globe.
For North Vietnam to win the war; which they did.
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.
It would be a close fight. China has more men to fight with. China also has more reserves. China has unquestionably better navies and air forces when compared to Russia, and around 9 times the amounts of tanks. China has the largest army in human history, more than the entire population of the United States. So, in a short war, China would win. In a longer war, China would win and begin to take Russian lands, eventually scoring the victory.This is of course assuming no nuclear weapons are used. Otherwise, China would also win.Answer:China would win without really trying.
Russia
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.
China
Russia. Russia could defeat any country except America and China, with or without nukes.
i would say russia because there a very big country
no china has much more men
