You're wrong because you're not applying nuance and you're trying to prognosticate. It depends on which part of Ukraine. All of Ukraine is extremely unlikely to be annexed because Putin is fairly contained by a multiplicity of international pressures. More likely, if at all, a portion of one of the Baltic states or a region around the Crimea would get take, but that's unlikely.
