Russia and china ect. would win. If it was to happen now, with our troops spread and our economic status. We have to remember that we are in heavy debt to China, they could crush us by themselves, economically. I would say China would start wanting the debt paid off, slowly weaking our economy, not to mention china has the largest army in the world and Iran has the largest paramilitary in the world. Russia has the most nukes in the world( the U.S.A. does not have over 50% of the world nukes like previously stated) and Russia dropped the largest bomb in recorded history. North Korea would be just added troops and supply routes. We would be fooling ourselfs if we didn't think nukes were going to be used. I see it going somewhat like China starts wanting the U.S. to pay them and when we are in a weakened state, i see China Invading california, and alska along with Russia. I see them taking Hawaii and destorying the militray bases in japan and south korea in the same span. Iran could keep the U.S. and allied troops at bay in the middle east with their huge paramilitary. I can also see Russia sending a nuke towards britian, or a couple, and like wise to the U.S. I give the advantage to them right now, if they attack first on a massive scale. They would win.

All of you just say that America is going to win because you lot come from the countries that are allied with the U.A.S, 40 countries are allied with the U.S:most of Europe and some countries in America.Plus I don't think U.S will fight the Russians.They hate each other but they are both scared of each other for example the war in Vietnam.It was U.S.A vs Vietnam.The Russians helped the Vietnam and they eventually won the war.Russia vs Afghanistan.The Russians lost unfortunately because the Americans helped the afghans a lot with the armory.The russians almost won the war but the Americans helped the Afghanistan.Now when it a war with U.S.A vs Afghanistan none of us know which country is going to win.Americans waste a lot of money on those lazy soldiers that if Russia will invade they would beat them and that will be when The Americans wouldn't be able to afford more money for soldiers that they will have to surrender.The same with the other countries allied with russia.

If the war will happen the countries will eventually bomb each other.Again Russia will have the advantage.If the Americans will throw the bomb at Moscow it is only going to destroy it and kill 6 million people out of 200.000 million.If the Russians will bomb Washington or miss the bomb will hit oother cities.Washington has a lot of cities surrounding it and only the part of Washington has people living there,the rest is just desert so the Russians have a big advantage.

If the Americans will attack the russians in Russia they might have that kind of war that The Germans had to face 80 years ago when they invaded.I know the Russians will fight anyone and that they can easily crush enemies some how with big army.Plus now one will take Russia,Napoleon,the racist dude called Hitler,not even the most powerfull people in the world managed to win a war against the Russians.So Russians,China,North Korea and Iran will WIN!!!

im sorry but Aus beat iran... Aus have nothing

You have mainly base the outcome on Airspace and America... Russia have a more advanced navy and much, MUCH more devastating bombs. America would be crushed by china NK and russia (Iran Would Supply The Oil And Bombs)

What's all this about Russia having a far superior navy? They really don't, ever since the collapse of the Soviet Union the Russian Navy (and other branches of their armed forces) has been in rapid deterioration. Russia claims to have 300 ships in service, but less then half are operational, and out of a fleet of 11 strategic missile submarines only 2 are in immediate combat readiness. One more thing, the Russian Navy is a green-water navy (Green-water navies are usually capable of sending their naval ships overseas on friendly port-visits, participating in joint-exercises with other navies and sustaining short-term regional deployments. But usually they either lack the ability for sustained long-distance combat operations or their naval-doctrine does not envisage deployments far away from their home bases.). So the U.K and U.S (I'm taking Australia out of the picture simply because I can't see how they would be able to help.) would claim victory in the naval battles (both are Blue-water navies, and both are the leading naval forces in the world). Air Forces? US and UK would claim victory, hands down, due to the fact they will be able to deploy aircraft carriers all over the world, and their superior aircraft. Ground battles? again, the US and UK would claim victory, China, North Korea, Iran and Russia have superior numbers, however with the better equipment and the better training, and better special forces, US and UK would prevail, and I'm sure you all know, it's quality over quantity (Battle of Britain anyone?).  Of course this is taking nukes out of the equation, with nukes, we all lose.
