Fair enough. Loads of problems with the TL I wrote thinking about it. Sorry it more of a thought process that went slightly out of control.
As for France and the Ottomans. I do mention that you would need a much weaker France and a much stronger Russia for the UK to ally with Germany. I would probably set a TL much further back, probably the Napoleonic Age where every couple of years a new government would fall, just to be replaced by the old one or a new one. Keep that going in France for such a long time it wrecks their industry and makes them fairly isolationist in comparison to the rest of Europe. That would make them weak enough for a prepared British and German invasion.
Russia needs to be a a stronger nation for the TL to work. That means the Ottomans need to be weaker. An earlier emergence of Arabic revolts, combined with a worse Crimean War would make the Ottomans much weaker. By the time WW1 starts, they've given up all pretense of empire and gone to being just Turkey for a while now. With the Ottoman threat removed, Russia can focus instead on building a better navy to support it's strength in the black see and building up an industry. Better trade with Arab nations and more open commerce in Asia.
As for the peace. I'm sorry I didn't make it clear with Ukraine, they don't get OTL territory. If anything they are about just less than half the size. Russian controls the (Can't remember name) big river that goes through the center of Ukraine down to the Black Sea. The Crimean Peninsula and anything to the west of the river. Their territory goes as far north of Kyiv. Japan actually only gets a little less than the Manchu territory from OTL. For Russia I wanted to emulate the defeat that Germany had in OTL. That's why the Autumn Charge is such a big for the Allies. The Imperial Forces had finally just been stopped within sight of the two most (arguably) important cities in Russia. The Charge was their do or die throw of the cards. They would either push the Imperial Forces back and defeat their armies utterly. Or Russia would lose the war. It was fighting a war on four fronts and didn't have the manpower left to defend all of them. Granted the USA could have made all the difference, but the one thing I wanted to get across was how difficult it would be to establish a naval superiority. The British couldn't do it in America and if things had carried on they would have lost every port in the Caribbean. The USA couldn't do it either. If it left small convoys of ships get to France or Russia then they would be picked off by the local fleets. The only way they would have gotten troops to France and did so, was with a huge show of numbers. A fleet so huge that the Imperial wouldn't be able to engage them, the problem being it would then have opened up their Atlantic/Pacific shipping to attack.
In my TL the Imperial Forces had no plan to try and take on the USA in it's own backyard, but if the Russians were forced to the table, then the USA would have to accept defeat. You can repeat how the USA was able to out produce both the UK and Japan in naval assets, but could it really out produce that and Germany? The Imperial Forces didn't have to invade the USA, nor wanted to. The US people would not accept to carry on a war that had already been going on for six years, when their Allies had already surrendered and their original reasons lost when Russia Surrendered. That's why the USA actually get's off quite easily. It loses a few islands in the Pacific, cut down on it's naval construction, lose some influence in the Caribbean and is forced to pay reparations to the nations involved.
