Despite all you say, Russia and China do have joint military and economic agreements. Look at all the SU-27 aircraft that are sold to the Chinese and now licence built by the Chinese. Look at the diesel subs, the Sovremmenny destroyers, etc.
So please, although I agree with you about the danger of Red China and the foolish way my country (The USA) is dealing with her, please do not patronize me about my knowledge of Red Chinese, Russian and Indian affairs.
Russia is clearly helping to arm China and using them (in what they perceiv as their own self interests) as a balance against the US to this day. Since Russia is eager to get the hard currency that the military equipment brings...I have no doubts that they would jump at a chance to exploit Siberia (while continuing to own it and control it) if the Chinese offered the man-power to do so for the right price.
As to China and India getting together...well, they are making noises now...but I agree it is also unlikely...but more unlikely things have happened in the past, like in 1939 with the Stalin/Hilter pact. That one took the whole world by surprise...and your Rodina paid a horrible price for it.
That's what these books are about...the danger of what could be. Before you throw around insults about them...try and read one or two. Nothing in there in any moreimplausible than what has already occurred in history, particularl the 20th century. And those who fail to learn those lessons from history, are apt to repeat them.
Russia and India know something we don't know: That China cannot escape its borders.
