Allies U.S.A, Britain, Canada, Israel, South Korea, Germany and Japan VS. North Korea, Iran, China, Russia, Formerly controlled Soviet Union States, and possibly Cuba.
China has a huge army but spends not much on it. I don't really know about the Russian army currently. I'm a bit biased since I'm American but I'd say the first group would win.
Ahh a naval one that makes me think of transformers. Since our navy is so big we could still point some at N. Korea. Not sure of its capitals distance from the coast though.
This is how railguns work they use immense amounts of electricity and to giant magnents propel a 7 - 10 pound projectile at speeds upwards of 5000 Mph with the force to blow the top off any mountain fortress.
but anyways, i realize this is hypothetical but realistically its some bs. a lot of that is very biased, because why would germany even get involved?? yes, it owes the U>S ,britain, and france in a way for rebuilding their country, but i see no reasons for them to be involved. the repurcussions of WW|| are still evident there anyways.
