If a war broke out, nation against nation, who would win?

Question

Who would win if a war broke out between every nation. Dont ask why just imagine. Who do you think would win and why or how. Feel free who would make alliances or be enemys... You deceide...

Answer 1

In the end, countries that are neutral, like Switzerland, Spain, and The Netherlands, would come out on top and take charge of what's left of the world, which wouldn't be much.  

Answer 2

America+Israel+European union= Win

China and Russia ally together

European union ally with AMURKA and ISREAL.

We all blow ecach other to h**l. Israel survives.

Answer 3

I know you want a "Fantasy Football" type answer, one that allows us to guess who's the strongest bully on the block.  But unfortunately, the only true answer is that NO ONE WOULD WIN.  One country might have more survivers, or less physical damage than other countries, but the bottomline is that we all would be damaged terribly by such a war.
