After the USSA

I was thinking about my previous post just now, and I was reminded of Kim Newman and Eugene Byrne's Back In The USSA series of stories. For those of you haven't read them, they're not strict alternate history (one description I heard of them once was 'pop-cultural fantasies') but they depict an alternate 20th Century where it was the USA that went Communist (and became the USSA - United Soviet States of America) while the Tsars retained power in a Russia which then became capitalist. One of the things that makes them not 'proper' alternate history is that Newman and Byrne mix real and fictional characters together - for instance, the President of the USA at the time of the (Eugene Debs-led) Revolution is Charles Foster Kane and the Vietnam (Indochina) War is told in the story 'Teddy Bear's Picnic', the cast of which is mostly from British comedy (think Apocalypse Now starring the Likely Lads) and features the classic line:

'Hello clouds, hello sky, hello pile of severed human heads.' said Major Basil Fotherington-Thomas.

The series of stories is complete, as far as I know, and Newman and Byrne haven't shown any indication that they're going to write more, but I've been wondering about how history would have continued in that world given that it's a kind of dark mirror of our own.

For instance, the General Secretaries of the USSA were figures from our world - Eugene Debs was the Lenin figure, then replaced by Al Capone ('Caponist' was that world's version of 'Stalinist') and by the time of the USSA's final collapse it was General Secretary Vonnegut trying to bring in his programmes of Getting It Together and Straight Talking before he was replaced by President John Ross Ewing.

The question I'm wondering about, though, is where does it go after that? Which character (either real or fictional) would be the Putin figure. Would the Rose Revolution take place in Atlanta, Georgia with Stipe replacing Saakashvilli? And what state would be the most likely alt-Ukraine?
