So how is life in the USSA, Russia, Germany, Spain, India, and the Arab Confederation?
How is technology?
Anything going up into space?
Anything about pop culture in this world we should know about?
I forgot to mention the space race. I knew I was missing something.
The Russians managed to land a two man team for June 28th 1975, having had to rush the project a bit more than they wanted to (launching almost 3 months early) when they managed to catch wind the Americans were aiming for a July 4th landing the same year. There would be significant outrage 15 years later when a retiring Eurasia Space Department administrator revealed the level of risks taken in the rush. The Americans meanwhile managed their launch two days later, the rockets having been more or less ready in case of bad weather forcasted for the actual launch date. The American mission and Russian mission actually had brief radio contact where the two crews congratulated the other, the Americans landing on July 1st instead of the planned July 4th, an event the rushing Space Exploration Bureau hadn't stopped to realise would cause supiciously enthusiastic celebrations in Canada. That team did return to Earth for July 4th, which sevred US propaganda well enough (though Canadians continued to celebrate 'landing day' a little too much).
Technology by this point is a little ahead of OTL, though not significantly. We're talking a couple years or so, and is a bit behind on some antiobiotics technology and the like (though pushing ahead with virology, Russians always prefered phages to antibiotics). As for pop culture, Ottoman cinema is the leading exporting force for world movies, though both India and the USSA actually produce more movies for internal consumption and the Chinese are starting to catch up to Ottoman production values (as for Russians, the regulations made starting studios in the Ottoman Empire easier so they set themselves up nicely there form the start and it's basically one system with more work done in Turkey which is marginally cheaper). Music has a lot more Middle-Eastern and Eastern-European influence, Rock And Roll is rather political here, being 'music of the revolution' and kept quite fifties (that's right USSA military marches with a more communist 'Johnny B. Goode' playing for television audiences is more or less right, in place of Red Army Choir music). Ballet is more successful.
As for life in various countries, things haven't changed
that much in the last ~8 years. The USSA has grown more dictatorial as paranoia over 'capitalist infiltrators' has grown to be the new big thing as the current triumverate try to distract from their growing power with show trial witch hunts (like mirror McCarthyism on steroids). Russia and surroundings are seeing more urbanisation and suburbanisation as people gradually grow richer, natural gas production is up and beginning to power large chunks of China and Europe. The Arab Confederation is actually starting to grumble about it as Iran and Eurasia drive down fossil fuel prices (and finding their bribing the populace for complacency more difficult) as such the Arab Confederation is stumbling towards democratic reform. Germany has finally mostly recovered from the 9 Years War, though they remain semi-bankrupt and keep seeing public service protests, still things are only about on par with OTL's UK's darker days. Spain is remaining weirdly friendly to capitalist powers while remaining solidly communist, but the economy only has so much going for it if they can't either make up with the USSA or Capitalists. India is sort of like Spain, but has a lot more people and has begun to compete with China as the 'mass produces cheap things' centre of the world.
Oh and I forgot to mention the collapse of the South Indian Confederation. Between communists and monarchist conservatives just wasn't stable, while the Hindu nationalist elements and pro-capitalists just couldn't find common ground. It kind of Belgiumed for a while, but with out an EU to argue about and far larger populations the various segments went their own way.
