I...wow. I actually am speechless over this last update, there's so much awesome detail that I really have not much to add. Here's my take on the update;
-Interesting how South Africa continues to expand their territory; I'm betting that OTL's Rhodesia (Zambezia and Brit. Congo here) will join at some point, which would be pretty cool and not normally seen in TLs (at least, outside of the Drakaverse and such). Would Madagascar be a possible addition as well down the road?
-Considering the lack of MAD/"Strategic Deterrence" as we know it, I wouldn't be surprised that America and Russia didn't focus on Boomer development at all. Frankly, I can see the former trying to get the most out of airborne assets (despite the lack of strategic bombing experience ITTL, it doesn't take a genius to see the advantages of air-deployed nukes in certain ways), while they and the latter could both look into ICBM development. I won't go too far into it, but ICBMs have their own advantages AND disadvantages that may or may not be researched in the TUF-verse by both parties. Your call, of course.
-The World's Fair and Chinese Succession issue both look good to me. I did notice how there's a Technocrat faction in China...are they anything like the Krulikists?
-C'mon, Western world, help Siam out already! They need it, and unlike them Japanese no-goodniks, they actually would be a good country to back in the region. America, Britain, Germany--SOMEBODY!
-The remainder of updates all look good to me. Of course, we just had to get another member of the Nuke Club in Russia.
