What does the quote Czar Alexander got to Paris mean?

Czar Alexander I, in defeat of Napolean, marched into Paris in victory. Since Stalin desired absolute victory over Nazi Germany in WW II, it is natural that he would contrast his own Russian Army capture of Berlin, and the takeover by the allies of the Reich, with the longer journey of Czar Alexander. It also holds out a high standard of what might constitute a "buffer zone" protecting Russia. The meaning is not "definite", but full of implications.
