Russian/Ukraine Geopolitics

What has motivated Russia's leaders throughout history?  What does President Putin hope to achieve by invading Ukraine?   Is the war becoming "Russia's Vietnam" or "Russia's Afghanistan"?   What can the West do, and what price will we Western citizens pay, to support Ukraine and push Putin back?  These issues will be addressed by Associate Professor Stephen Hoadley from The University of Auckland.  Stephen is a veteran academic, author, and media commentator on international affairs.  Originally from the US, he is now a NZ citizen.  He has served in the US Navy and is now an Honorary Captain in the Royal New Zealand Navy.
