I agree 100% up until you get to the part about Austria and the Sudetenland (it was not all of Czechoslovakia).

Russia is not (IMO) trying to get more "lebensraum" like the 1930 German Nazis. They are trying to avoid becoming another Yugoslavia, Libya, Syria and/or Iraq.

A (not "the") goal of many at the top in the US is to balkanize Russia so that they can go back to the finanicial raping they enjoyed in the mid-90s after the fall of the USSR.

The US has been systematically destroying / trying to destroy / occupying Russia's allies since right after the USSR fell.

This is all part of the "Wolfowitz Doctrine."
