A few points:
-WTF Iceland?
- SRJ still exists, but Macedonia is in an alliance with Albania
-Arabia: The pinkish Yemen implies that the UAE no longer cooperate with the US, and that implies the Bahrain naval base is no longer US-held. This would go a long way to empower Iran, as well as keep the emirates from stirring shit up. This would also give Iran immense power over the oil supplies of the middle east. The weird part here is that Iran isn't there in Turkey's place, since it's 75% Shia.
-Asia pivot: Would an economic collapse of the US drag China along with it? I mean, they are diversifying(although there doesn't seem to be any yellow in Africa on that map), but their growth is also slowing down. A total implosion of the US would shock them very thoroughly. Considering the CCP mandate is, implicitly, providing prosperity, perhaps shock them enough for... drastic consequences. This could be why Iran is as prominent as they are: it's not that they surged as much as the rest of the world fell around them. This, however, would raise the problem of India: if the US goes under and China follows, India would need to implode to not come out on top as the dominant regional power.
-Turkey: Hard fought by whom?
From Mustafa Kemal to the end of WW2, Turkey was, in effect, a one party state. The secular right were in charge until 1950, when they lost to the left. 10 years later, the army staged a coup, in order to "return the nation to the proper course" (purge the commies). Next elections, left won again, and 10 years later the army had another coup, to "restore democracy" (purge the commies). The next decade was a whirlwind of coalitions of the left, right, even islamists (One such 'right+islam' coalition invaded Cyprus.), capped off by one more coup, in order to "unite the country into a global economy" (purge the commies). What followed was a decade and a half of relative prosperity (and a guerilla war with Kurds/Marxists) straight up until 1997, when islamists were elected, and the army 'asked' the prime minister to step down.
Which brings us to the 21 century. The current AK-Party (no relations) is of the "not islamists, honest" variety, got into power in 2002, and is still going strong. At this point, Turkey averaged a coup every 10 years or so, so what gives? Well, there's the arrests,also the arrests,and let's not forget the arrests. Essentially, an islamist Turkey is not at all unlikely by 2035. The problem is that, unlike Iranians, Turks are Sunni. Now, during the cold war, the army secularists skewed heavily pro-NATO, while islamists yearned for the days of the Ottoman empire. AKP, however, continue to pursue an EU membership, at least optically.
This opens up a possibility: the arrests in the last decade and a half would indicate the Turkish military lost NATO a powerful supporter with the cold war dying down. A failing US, dragging EU down with it, would damage AKP, and the military could leverage the far-right into one more coup. This would make them both secular (like Iran presumably is) and anti-west. Also, the nationalists would have no problem with hating Greece. And, more importantly for us, this would give the military alliance Turkey is a member of every possible reason to get involved if, say, an island off the coast of Greece were to, say, go and declare independence and then descend into a civil war.
As a sidenote: The issue with oil isn't that there won't be oil. There will be oil. We can make oil. We can literally synthesize gasoline from thin air if we need it that badly. What there won't be is cheap oil. It's not "oil crisis", it's "energy crisis". The thing to note is that the price of everything and anything consists of material+labor+energy. For the last century, oil was so cheap that, basically, energy=oil=0. The whole deal with renewables is to change 'energy=oil' before 'oil!=0' makes food a luxury item.
Another thing I find interesting is that all these near future scenarios seem to just take for granted that this whole climate change thing kinda blows over on it's own and has no impact on anything
