Americans need to stop being braggerds and realize that a combined effort by Russia and China would kick our asses clear into next week... Sadly, the only deterrent is a superior nuclear arsenal. OneMy scenario is based on Russia and China working together first. Their combined troop strength alone sweeping through central Asia and driving into Europe by way of Turkey and the Caucasus would be enough to make it to France and give Britain diarrhea. America wouldn't be entered, but our military would most probably not survive fighting at current personnel levels. And the most likely final scenario would lead to either limited regional nuclear exchanges or an all out global incineration. The best choice would be for all parties to do the math and stand down in the first place. But, mankind just can't get enough of the game of war...
