Are there enough nations on Russia's side to call them a bloc? It seems like almost everyone is supporting Ukraine.
India and China are both supporting Russia in various overt and covert ways. That's a huge fraction of the world.
Iran is even more closely linked. Arguably the real reason for the American attack on Iran is to reduce their contribution to the Ukraine conflict.
Plus Russia's various Toadies (which included Hungary, an EU nation, until recently)... It's a pretty sizeable bloc.
It's not yet an all out Axis and Allies situation, but it's definitely not just Russia against the world.
China is a bloc unto itself
North Korea is definitely part of the Russian bloc now.
