Hmm. Given the way this map is, I'd expect a PoD in the 1970s at the latest. Otherwise, as has been pointed out upthread, why aren't Italy, Ireland, Spain etc in the EU?
For a PoD in the 1970s, how about having the Yom Kippur War being a more dramatic Israeli victory? For instance, deploying their reserves to the Golan Heights a day or two earlier would have made an even bigger mess of the attacking Syrian forces. There's a good argument that it was the (relative) success of the Arab nations which allowed them to feel less humiliated and thus to the Camp David Accords and (relative) peace between Israel and the Arab nations since. Without this, as also mentioned upthread, things could continue to get quite ugly, with wars in the Middle East every decade or so.
And also, I'd also suggest some minor amendments to the map. Viz, I really can't see Australia holding down Java. As of today, it has about 127 million inhabitants and Australia has 20 million, and the percentages are only likely to be further in Java's favour by 2090. Ye gods, occupying something like that would be a challenge. Maybe India could do it, but Australia... I rather doubt it. I also suspect that if Australia has been grabbing territory off Indonesia, Irian Jaya would be on the list as well. Certainly ahead of Java.
