What would the world be like if the Soviet Union survived to this day? I think that it would just be cool, because the USSR and USA were very similar. Both had constitutions gauranteeing freedom of speach, religion, etc.
Perhaps the Soviet Union would change to democracy with the continued reforms of Gorbuchev. The Soviet Union wouldn't be exactly like the United States, perhaps with a more parliamentary system, where each SSR has elections for a representitive to the Grand Soviet every 2 or something years, and every 4 years they elect a General Secretary or something. I'm not too familiar with the Soviet system.
It would truely be a freaky twin of the US. It's just funny to think of how despite their differences, the US and USSR had a lot in common. The US throught it's history hasn't exactly been an angel, keep that in mind.
So, if the Soviet Union managed to keep itself together, what might the world be like today? It's likely from 1991 to 2008 the USA and USSR would be a bit more friendly. Despite some difference in interests, the Cold War wouldn't be too much of how it was during the late 20th century. I'd like to see an alternate history fiction where the Soviet Union and United States work together to fight terrorism and yada yada.
