Some others that might be worth it:
U01 - Burma
U02 - Egypt
U03 - Israel (?)
I checked. Egypt is already there. Israel is not. but palestine is there. (Can't we just rename it??)
Burma is also already there. So is Indonesia, Indochina (!)
Morocco, Algeria, Tunisia, Libya, Brunei, Malaysia, Syria, Lebanon, Croatia, Slovenia, Russia w/ all those rebellion states (Ukraine, Byelorussia, Azerbadsjan etc.)
so we do not have to add THAT many to make a map more like todays. If C.O.R.E. starts to move further into modern days, I think it will be hard to make the independence of the African colonies. I tried, but there wasn't enough tags for the south-western states and the central-states. (And then I used the old copuntries and renamed them!!!)
