I think its useless to compare the two, but without China NK doesnt even exist as a communist state.

There is no value with Russian foreign policy right now, no mass movement to use the potential for heightened class contradiction. Besides, modern day Russia is just the hotbed for disguntled nationalists who only exist with even a modicum of power because of US strategic interests. The ideology guiding the ruling class of Russia is bland, incompatible with the concept of class struggle, and archaic. I see Russia to China as Canada is to the US. Do I really care that Canada may have better standards than the US or better foreign policy or better whatever? No, not really. I'm looking at countries that can actually do something useful for me, and the choices are between the US and China, not between Canada and Russia.
