If Russia wins the war, how many other countries will they invade?

Russia's offensive capabilities are already languishing now and they have barely captured a 1/5th of Ukraine. It's going to take them years to rebuild their military, especially if they are still under heavy sanctions.

I'd like to see how this conflict ends before guessing, but I would say Georgia. Belarus is a client state already, and Kazakhstan is probably too large for Russia to successfully occupy. The Russian military's logistical capabilities are just terrible. If Russia fails in Ukraine, and Putin is still in power years from now, it's possible he might want to reorganize & rebuild his forces to try again, but I doubt that would happen for a number of reasons. One in particular being how well-armed, well-trained and fortified Ukraine is going to become if Russia pulls out or a stalemate along the current lines (more or less) occurs.
