"Who rules East Europe commands the Heartland;who rules the Heartland commands the World-Island;who rules the World-Island commands the world."
-Halford Mackinder
The Russians are facing a demographics crisis, braindrain crisis and their economy is a mess based on natural gas. They are surrounded by rising economies and their western enemies are only 100km from St Petersberg. Under Putin they've been able to take back central Asia and halt the west in Belarus in Ukraine but as a result NATO has become autistically focused on them. They're an insanely resource rich country but their numerous problems make it hard for them to actually exploit that advantage.
Can Russia remain a Great Power? Or is it fucked? Or perhaps its already lost that status?
Most of their country still identifies as Russian so there isn't much chance of them splintering and they have a strong central govt so foreign influence is hardly a problem. The big issue seems to be economic collapse. Russia has negative population growth and its really bad. I don't see Russia becoming a puppet or divided up but I do see them becoming as irrelevant as Brazil is now. The US deep state seems to be really focused on destroying Russia but that seems to be more of a elite-manufactured morale panic to distract people and acquire more power.
