China and Russia launch naval exercises in Yellow Sea，aim at US?

Ain't going to happen. Neither China, Russia, the United States, NATO, or any other country can afford to go to war with any two sides. The ultimate and extreme cost in a war of this magnitude would outweight any benefits that came along with it.

Hey genius, the cold war ended a long time ago. Russia is not a communist state anymore. They are VERY good friends with America and many other Western nations, their GDP has increased dramatically without communism, their income per capita is approaching Western averages, they are a prosperous nation with no need or want for war. It's downright stupid to think they want to take over the world and march through times square with colours flying. Just stupid.

The us, but nukes will be used, and therefore no one will win. Here's the no-nuke story. China and Russia have ONE aircraft carrier to transport all of their troops across an ocean. The us along has 11, plus 9 amphibious assault ships with flight decks. NATO would come to the aid of America, bringing like 5 more aircraft carriers into the picture. In sheer manpower, Russia and china would win, but it wouldn't come down to that. The technology of Europe and the us would win out before manpower became an issue. So the us would win.
