Putin hasn't been trying to increase his sphere of influence, unlike the US and the EU. Putin seems more interested in keeping up the status quo, which to me is a more preferable situation.

Note that the US has army bases all across the world and instability in many countries has been caused by US policy. Policy which seems to be guided mainly by business interests:
