Very nice indeed, LSC.

It's the future, but not our future. Humanity made it through the Scary Century with only a couple minor nuclear woops, and the interventionist, pro-technology great powers managed to deal with the effects of global warming without too much third-world ghastliness. Robots and cyborgs are plentiful (although true AI remains elusive), fusion now powers the world (although the colossal fusion power plants are even more capital-intensive than the old fission ones), and the human average lifespan now exceeds 130 years (although mutant new versions of the Common Cold still crop up).
Currently, things look hopeful, with three of the Great Powers now (more or less) democracies and the theocratic Chinese government not being the Spread It By Fire and Sword kind of theocracy. The current biggest worry is the cleanup of South Africa: long supported by the Reich, the South African "racial state" went into isolation after the Reich withdrew support, and finally crumbled in a civil war of genocidal savagery and mass ethnic cleansing finally put to a halt by forces from all four Powers.
Butterflies and a lack of a globalized economy meant that Chinese modernization didn't go as well as OTL, and what with the impact of global warming in the 21st century, things went pear-shaped for a while. China didn't quite reach the Number One brass ring in the 21st century, but there is still quite a bit of the 22nd to go, and they are certain than the many odd gods of their faith are on their side.
The US has managed to avoid population shrinkage due to continued immigration, and although still less populous than China is rather closer in numbers than it was a century and a half ago. It is no longer the world's largest economy, that being India, but having won the long struggle for influence with the Nazis in South America, the US and its allies are the most influential of the four Blocks. The British Commonwealth is pretty much a federal state nowadays. "Free France" or "France in Exile" finally saw the end of the German rule and democracy return to their homeland, but after a century and a half of cultural divergence and intermingling with the natives, the scattered francophone community finds itself unwilling to rejoin an alien homeland. (Something similar is the case with Christian and Buddhist Taiwan and the Falun-Gong like faith of China).
India dominates the "Indian Ocean Rim" and has the world's largest space-based industrial machine, but worries that its poisition as Number One is in danger. India passed China as the world's most populous nation a long time ago, but China is now catching up again, with the pro-natal religious culture of China growing while rich, secular India suffers from shrinking population: not so much of an isue currently, since Indian robotics and cybernetics are good enough to make up for a lack of labor, but the huge population of over 80-year-olds which own everything is alientated badly from their cyborged, gene-tweaked, drug-raptured great-grandchildren.
The Reich has democratized and given liberty to most of its subject peoples, although the closely integrated economy of the European area remains German-dominated. Greater Germany is densely populated, with over half the population of the US, thanks to a century and a half of vigorous (take-uncooperative-non-party-women-off-to-the-rape-camps-vigorous) pro-natalist policy, and remains a formidable industrial power, but in spite of great improvements in economic conditions since the end of "Fuhrer rule", Germans feel they have given up too much and slumped to second-rate status in the last half century. The plunge in the birth rate since democratization worries many German pundits, and the efforts by the French and others to reduce economic dependence on the Reich through closer economic ties with India and the US raises fears of a complete disintegration of the "German Sphere..."
