I think part of the interventions in the liberation of Palestine and Turkey might involve a take-over of Iraq, enough for the Gulf states and the Saud family to go FBU.
In terms of Egypt, it seems that the Nasser overthrow is more of a product of the first draft than a latest version, but nothing much is said about Egypt's fate in the retcon. India is the biggest change, as a FBU mainstay, as well as Latin American revolutions in the 30s, than Latin American bourgeois governments receiving Comintern aid, and then just turn Red. In hindsight, it's not a sound concept. I think not much is going to change on the fate of Egypt of becoming a postwar republic, probably a lingering effect of Labourite governance, then as the Cold War gets more heated and Nasser asserts himself, a coup to solve the Suez Canal crisis might occur. During this time, a PLP administration might be in power in America to further smoothen the coup operation, since DeLeon-Debs is not going to interfere.
Afghanistan seems to be not much of a capitalist island, I stand corrected, thanks to having a border with FBU India. It's more of a capitalist hinterland. However, Afghanistan might be in a unique Thailand-like situation of staying free from dominant international squabbles or even becoming an Asian Switzerland. It might be even agreed for the postwar partition of the world that Afghanistan should stay where it is and the Afghan ruling classes also will have a motivating factor to stay where they are in the social order and to keep foreigners out of the country, especially the commies.
In terms of the rapes, I really thought that the more thorough social revolution of America might really affect the hyper-conservative and patriarchal Soviet Union, thanks to the liberated Americans. Sexual repression would be less among Comintern soldiers of the Soviet front so less need for rapes or going to brothels or provide soldiers with prostitutes and stuff since the rather more sexually open and aggressive American women of the time were around to relieve those repressed feelings, the military command would not tolerate opening brothels for soldiers, an added bonus too is the militant feminism of the female soldiers that you've already had sex with once or even your girlfriend/s, sweetheart/s, fiancee already that is going to condemn rape, especially war rape, from the shared communist ideology. The USSR has to fight for the title ITTL so it have to behave due to American pressure. From a certain viewpoint (American), the best revenge on the fascist enemy is communist conversion, and you cannot create mass converts in an enemy country by doing such atrocities, only creating more anti-communism and worse, a prolonged insurgency. I don't think the logic of "degrading the enemy" is a sound logic for a soldier living in a new society (at least for an American) as well as the understanding that stopping a revanchist Germany/Italy from rising is to treat the country well despite being a defeated enemy. Basically, the lessons of World War I really taken into heart. These soldiers are also well-provisioned and well-disciplined by the giant communist arsenal that is America, plus the power to elect their commanders, a sense of ownership of things rising, including a military run by soldiers. I'm not sure of seeing cases of war rape to reactionary women from the side of anarchist militias during the Spanish Civil War in OTL, despite decades of repression by landlords, the Church, etc. If America really has a Spanish tinge to it, even for a bit, it would be enough. The more socially open wartime environment of the USSR, the presence of Americans, death of Stalin... will create the conditions in my opinion that sexual repression is lessened and such sexual feelings is already directed towards women in their own midst than the prospect of raping conquered women. It's... just so reactionary. A product of the past.
I think the FBU might deliriously try a rollback that is going to spectacularly fail, but it would be too late to take back the losses. By that time, it's all over. All it can do is to maintain a posture of stubborn defense or "open up", that is go more socialist even in rhetoric... but skillfully keeping the system intact under that more socialistic cover. A two-party system of reformist socialists and modern One Nation tories, but the hints are still much on a continued LDP style dominance from 1947 to present. So even better, the FBU is really doomed.
Just because the FBU is demographically and geographically smaller than the Comintern doesn't mean that it can't survive long. For me, one of the biggest reasons why it can survive is because the Comintern is not only divided for 3 decades but also because even at 2010, it is still remotely connected to capitalism through markets, foreign trade and the privileged state apparatus in conditions of continued resource scarcity as well as the recovery period from postwar mass environmental degradation. I'm not optimistic on the prospects that the Second Cultural Revolution really accomplished a lot. There are significant accomplishments, it's for sure, Soviet democracy can provide a limited avenue... but they're not that far-reaching. Cut the FBU from trading completely with the Comintern and have the Comintern develop a full Bookchinite/Venus Project style post-scarcity cybernetic ecological demarchic anarcho-communist society... under a foederati of communities, if it's even possible to do... and the FBU might fall spectacularly very fast. But it's not going to happen immediately, even if the technology might be there for a full international demos and polis to arise. The managerial-coordinator classes and the American military establishment relying on the remnants of nationalism, industrialism and classism within the Comintern with the added benefits of a permanent Cold War economy would have none of it. The struggle continues within international socialism. World revolution continues. The concept is getting more Gramscian than Trotskyist by time.
