What were Stalin's objectives in supporting Communists governments in Eastern Europe?

Stalin had only one objective total power at any cost

He was trying to spread Communism, and on the way make him kind've hte "Leader" of communism. He was basically making the communist countries be exiled from the west of the world, so he had pure trading beneifts with them, $$ galore. Plus more communist countries=bigger army to take over the US.

To rule the world by force. Remember he said "WE WILL BURY YOU". While slamming his shoe on the podium at the UN.
