Long term perhaps, maybe not short term.

All the European countries (especially East European ones) have started to slowly warm up to Russia, and by that I mean stop believing it is their ideological mortal enemy and occupier. There was some inkling of "hey maybe they are civilized enough to start doing business with".

This now has rolled all that back to Soviet Union times. This will not destroy or kill Russia, but it will increase the rift between itself and the West.

In the short term they have the gas resources and they have the military might (and now the additional port and more land). So from Putin's pragmatic short term view he is winning.

In the long term, Russia will become more isolated. So it is a bad move long term. This will not be forgotten for many generations.
