It is interesting you brought up Neville Chamberlain, not many people even know who he was.... A lot of people openly protest the war in Iraq, however the question of what if we had not gone in and something would have happened... Bush would have been blamed by the same people for not going in.
Getting back to Russia...Russia is waiting for the power shift as America dives into more debt as a nation and becomes more willed against war. China will over-inflate itself and fall into a depression (just like the US did in the '30s) followed by a war. During the cold war Russia had the most troops on the Chinese border, not the NATO border... Russia is nervous about China's development and will seek any oil control to gain leverage economically. Russia will be in the economic spotlight just as soon as China's economy over-inflates as they will strategically control oil interests.
The only problem facing Russian development is their own corruption.
