Some thoughts and ideas for the future:
Germany & Berlin becomes similar to Weimar Germany on steroids (with a more stable political base and economy) with a dash of 1920s Paris. Radicals, Leftist Intellectuals, Artists, writers, club goers, a variety of people who experiment sexually etc. Whilst the government deals with the problems of a Kasiern and variety of Goverments. I'm guessing Europa would be a bit similar.
Persia becomes similar to Turkey but bigger, deciding to become more tolerant of religions mainly to get more supporters. However it does deal with some problems from a mixture of groups.
Portugal survives for a bit before Europa tramples it into dust.
Ireland and Britain become like Korea (before the 00s) for a bit, lobbing shells and bombs every so often and becoming increasingly paranoid.
