So this was paid for and published by Commintern, The Communist International, also known as the Third International which operated from 1919 to 1943. This was published in the 1930s while Joseph Stalin was in charge.
The fact that some people would post this unironically when the person who sent this message was notorious for the iron-fucking-curtain is beyond stupid.
We can acknowledge both that, the original Creator had bad intentions for the US and the message rings very true today.
Originally this message was designed to weaken the US. Today this message will strengthen the US. Time has changed the material conditions of the world.
My current opinion is, a message can be good or bad regardless of the source. That can have exception when there's hidden implication of support for evil deeds (ex. all lives matter). In this case, I can recognize the truth in this message that still resonates today and don't see the implication of support for the entirety of Stalin's actions. Also, bringing up the iron curtain is actual pretty ironic, given that was about isolationism and this comic is (at least on the surface) anti-isolationist.
