Yes, but the point is you can start with a plebiscite, in which the people want to join the other power (Austria/Germany or Crimea/Russia) and then you move on to other cases where "it just makes sense" that the larger power move in to "rescue" their brothers on the other side of the border (Germany/sudetenland or Russia/???).
I continue to believe that the US should let them all sort this one out, but an old pattern may be re-asserting itself, and if we weaken ourselves while the pattern grows, we will find ourselves with few options, and that is just never good.
