Hate to say it but, wtf does this mean anyway? Does the left have anything to offer to Russia, China, etc? What does it mean for us to support them, or to withdraw our support?

My honest and most realistic appraisal is that our support means nothing, we have nothing to offer, and any engagement in discourse about the moral or political value of the projects of the Russian state or the Chinese state is basically fruitless when the discussion among those in the halls of power is so far removed from our discussion that the difference between the most fervently critical Anarchist comrade and the most ridiculously pro-SMO ML is completely irrelevant. It's not exactly arguing over how many angels can dance on the head of a pin, but functionally it's just as useless of a discussion. If we all agree that we have to show up at protests resisting the MIC, calling for peace, supporting leftist local politicians, and doing everything we can to raise union membership, what difference does it make that I 'stan China' but you 'critically support Putin despite Duginist elements in the Russian government'? Is it not just as fruitless as political compass memes? Because from where I'm looking it literally is just PCM for people that have read the manifesto. The only value of the argument is to intellectually deduce the truth, a project that's completely separate to actually achieving political power.

And yes, where you land in the spectrum of supporting Russia and China can influence which political party in your area to support, but practically the only material difference a minority party will make is whether it's going to support sanctions and tariffs against Russia and China, or it won't. However, not to No True Scotsman, but no true leftist party is going to jump on such a blatantly neoliberal and imperialist position as to economically punish 2 of the largest populations on Earth while knowing how little effect those sanctions will have on the ruling classes of the target states. So we're back to square 1, regardless of your position, the actions you can take regarding Russia and China are the same.

Just to finish off the rant, here's a comment from 72T that I found really insightful. TL;DR the question isn't, "should we support a multipolar world," because we have no power to change that reality, whether it's going to arrive or not is entirely out of our hands. The question is "what is to be done about the incoming multipolar world," especially locally, with regards to how it affects our approach to building power.

No shade on JT though, as far as the question exists in a vacuum that's a good answer.
