Unless their plan includes creating an army of soldiers raised from the dead (they don’t have access to glorious Juche necromancy) they simply have no plan that can compete with Russia’s tenfold population. And that’s that Ukraine has had a general mobilization and has switched to a war economy… of which Russia has only had to moderately elevate their conscripts and their economy is fine or even better than before the war.

Realistically they are hoping to drag the American military to put boots on the ground, a very very unpopular position. Even for liberals that hate Russia with every fiber of their being.
