but it would seem that the “withering away” can only truly be achieved through global proletarian dictatorship. Maybe that’s how Lenin and Marx felt at the time they wrote their texts, that global proletarian revolution was just around the corner.
I would say yes and yes. It was the assumption of communists in russia that the german revolution would soon follow after the russian one, which would kickstart revolutions in europe.
one thing i want to point out is that a lot of trotskyists use the logic of “the state can only wither away after a global revolution” to argue that revolutions on the national level are useless (and that no AES state is actually revolutionary / communist). which is why they always organise into international parties
The Corbyn party is still hypothetical, nothing has been formalised yet. The 15% is purely based on his name recognition / hate for other parties. I assume when they create an actual program and campaign the polling would change a lot
