It wouldn't be really dystopian with a WW2 being a lot more unlikely here as France would be way too weak in industry and economy to be able to beat a superpower Germany with Britain recognizing the loss redirecting its focus towards its colonial empire alongside even if the USSR or a fascist White Russia takes power they would significantly lag in industrialization compared to otl with much of their valuable territories under German influence and a second front war so the entire power of the Kaiserreich doesn't swarm them. The worst it can get is if decolonization is delayed to decades after with no UN and superpower USA with the destruction from WW2 pushing them to let go they will try to continue to lord after Africa either through blood and guts or the signing of a "mutual contract" it doesn't change that the old world's prospects will be alot grimmer even if its freedom was harder to gain alongside in the topic of empires a sun would have found its place in the sun ever rising as per its namesake with America either losing or staying out of WW1 isolationist feelings would be much more prevalent meaning no embargo on Japan if it attacks China or British and French Asian colonies out of fear of provoking the sun while there may be pacific war but not by the US but by the empires of old and the new facing off to gain rulership over Asia with Japan winning just by distance alone with all the funni moments Asia would have to face otl over years turned to decades as imperialism in name chains them down while being fed crumbs from their "liberator"
