The U.S obvoius
There were no nukes in WWI.
They do not have the technology to reach each other.
Russia. They have way more nukes then China.
There was a war and Mexico won by dropping twenty nukes on texas.
Depends on who pushes the button on the Nukes, but without those I'd have to say Britain.. Side note: There are no winners in a war.
If they fought a limited war it could go either way, depending on the circumstances, but I have trouble envisioning a limited war with nukes. Once the first nuke is detonated, it will probably lead to more nukes, with no limits, and no winners.
An atomic power can't declare war, that would imply using nukes. The last time the US declared war was in WWII. And nukes didn't exist then.
Nukes.
They both have nukes, so we would all be dead. But excluding nukes, russia have a lot more men than Britain so id say Russia
right now... Still Japan. Pakistan they have nukes :)
No. there would have been a war if the nukes were launched
Start WW3 by launching nukes
