There is a lot of factor in play here. First it will likely take at least 50 years for the former CSA and maybe Canada to cool down enough for the United States to become whole enough to concentrate on what is happening abroad.
Secondly there is interesting factor. United States have access to oil all around her empire and I am sure that her purpit regime in Mexico will give her the rights for drilling outside waters of Mexico too.
That's not really a factor of the Cold War, you could argue. While the Soviet Union had to do something similar in OTL for its satellite nations, the U.S. isn't the USSR here. The places taken over are going to have to deal with being what they are: U.S. territories and possibly states someday. They don't like it? Well, I'm sure that they'll probably get an even tighter draconian control on their areas if they get funny with the U.S. Sad as it may be, that's how it looks for the future.
Also, no doubt that Mexico will probably begin to supply oil anyway, as she's so economically tied to the U.S.
Germany, however will only be able to have steady flow of oil from Romania, cause its the Russians who are sitting on the biggest supplies in Europe.
Assuming, of course, that Austria-Hungary doesn't try to hoard all the oil for itself (sure, Germany may be able to pressure her a bit, but Austria-Hungary may attempt to resist a bit, especially if they begin to get more and more paranoid over their own sovereignty) remember, the Kingdom of Romania is an Austrian-Hungarian puppet,
not a German one.
Germanies allies in the Ottoman empire will yes be able to drill for oil in what is OTL Kuwait/Saudi Arabia, but I am sure that arab nationalists maybe with help from Russia? Will try to disrupt this. Hurting German industry!
The Ottomans pretty much stopped being friends with...um, anyone as soon as they set up the Independence Movement. I imagine, though, that they're going to still keep business going while all the while supplying rebels in other nations. I'm going to imagine that, as David said in a PM to me, they're going to become very rich as they begin to westernize in this decade (opening up her borders for immigration and trade). If Russia's smart, she'll stay down and not try to incur the wrath of Germany again, and I don't think the czar is in any position to try to do that either, what with being drained against a small war with the Empire of Japan and the Second Great War.
Japan needs oil too but where to buy it from? Russia,Germany and United States will not sell it to her, and thusly only place to get is Indonesia.
Then she's going to face a big oil crisis sometime in the future, obviously. And Japan may to concede several things if she wants as much, especially if things like cars, etc. become more and more popular in the empire.
Maybe Islamic Nationalists will try to prevent this?
Please just...how many times do we have to say it? Muslim extremism will be a non-issue here because the Ottomans won't tolerate it. It threatens the security of the empire that they have, and coming close to dissolving around the Great War's time, they're not going to probably ever take that chance again.
So lets look at it. Ottaman Empire and the germans will have to commit a hudge level of troops and resources too hold down a possible insurgency in the Middle East and if Japan doesn't get a steady oil supply from Indonesia, it will hurt her too.
Um, no. The Ottomans will most likely bar the Germans from her borders if they try anything cute. You're also underestimating the tenacity of the Ottoman military at this point: as another commentator here noted, any sort of revolt, Arab or otherwise, is going to be eaten for lunch, no questions asked.
I perdict that the Japanese and German economies will start to suffer from this in the 1960s maybe early 1970s.
Maybe resulting in a breakup of German, Japanese and Ottoman Empire in the 1980s.
The Japanese and German economies? Maybe. The 1960s is going to be a turbulent time for...everybody, I'd say. The Austrian-Hungarian empire may break up around that time (especially if a recession hits in the '70s, I'd think...), or it may become a parliamentary democracy. I'd say the Ottoman empire, and maybe the Empire of Brazil, will probably be the only 'true' ones left by around the year 2000. After all, the O.E. has lasted for around over 600 years, who says it can't last more? Actually, by 1999, she'll have reached her 700th birthday.
Leaving Russia, Brazil, United States the strongest Nations on Earth maybe by 2020. and by 2050 United States will have scooped up her sphere of influency maybe simular to the one in OTL?
Honestly don't think Russia's going to be a super power here. She hasn't even industrialized most of her areas it would seem (at least by the 1940s), and that's going to take some serious shifts in governmental control if it's going to happen at all. While the U.S. may be the most stable in the sphere of influences, they still may be relegated to sharing the seat of power with a still strong Germany and Japan, if they fall apart. Once again, the Empire of Brazil is probably going to get her own sphere of influence in South America, and possibly be the new and emerging super power as well.
