As someone who doesn't align with Anarchism. I think this is a weak vector of rebuttal against Anarchism, because there's plenty of non-aggressive treaties and other pacts signed between socialist states and mortal enemies. They can just point at Molotov-Ribbentrop pact for example.
"Stalin had to sign a pact with these guys to buy time! We had to do it with these guys!" It's not exactly difficult for them to do it and therefore I think the question is deeper than that.
You have to ask each group specifically why did they do that, what are they hoping to achieve and what have they achieved?
A Modern day equivalent of a mind breaker would be China-Israel relations. I personally haven't heard of a proper Marxist analysis on that situation. On an emotional level it's at least on par if not worse than someone collaborating with CIA, but I'm supposed to rely on more than gut instinct aren't I?



You aren't wrong. Our Anarchist movements are currently being infiltrated by a certain flavor of blue and a touch of yellow, but I can't think of a way to actually do anything against it. They use plausible half-truths that I can't simply deny, but an actually nuanced argument would get me eliminated.
And being a martyr for such a cause is not productive, because the headline would read: "Mentally insane woman defends Putin's Russia"
When my family hates Putin for selling out the USSR and they know it, there's a propaganda channel aimed for boomers and they do literally use that talking point to appeal to ex-soviet citizens. They're quite clever I hate it. But to Anarchists truth is often black and white. Ala Big country attacks on small country, big country bad. It is actually a lot more nuanced than that.
Anarchist are like Skull Face from MGS. Big ambitions, toddler discipline.
"Waaah English bad language gonna ban English and fix the world!!"
"Waaah give every nation a WMD!!!"
What even is a Nation? Why Isn't there a Székely Republic? What about Basques Republic? Should they have WMDs?
Should Micronesia have Nuclear Detents?
Dangerous topic for me to discuss because there's a meme floating around about how there's separatists in the region that borders Russia. I mean seriously? My ass would get bombed to stone age by this foolish meme of a proposal. It's dangerously ridiculous. Sorry if I sound overly passionate I'm just really depressed about the suffering happening literally in the same spot my ancestors went to battle in the hopes that they would never have to go to battle again.
But yeah that's Anarchism, it's not much different than Trotskyism. I will work with them critically, but not take their assistance for granted. Best way to handle them imo. Extreme caution.
