What a lot of complex questions.
Fair enough. America certainly has the money, resources and manpower pool to be considered as such. I just wondered if there would be ‘parenting’ of combat units until up to speed. American units can be assigned to quieter sections of the front I suppose, while CinC US gains a seat at the top table.
I have to tell you, that I think Teddy's army would still have problems with outdated tactics and operational art. I would like to think that whoever Teddy chooses as ground forces commander would be wise enough to "train up" with the French. Teddy, himself, would be far more cognizant of the need to train up and get the AEF up to speed, than Pershing was, having personally participated as a field grade with the First Volunteer Calvary in the land campaign shambles that was the 7th Corps operation at Santiago de Cuba. Kettle Hill was a disaster and TR was a part of that fighting. Helped to retrieve it. Roosevelt knew that storming a trench line was not as Pershing "imagined".
Expect Mister Roosevelt's army to go machine gun shopping and to be keenly interested in tanks and mobile artillery as soon as the proper officers see those items. Ditto airplanes as in BOMBERS.
Is there a chance the US declares War only on Germany, limiting combat to just US vs German fronts?
TR was smart. He knew where the heart of the CP was. And, unless the other Central Powers wanted a piece of the US, why go looking for a fight that dissipates the US effort? One front at a time is just as true in WWI as it would be in WWII. More on German New Guinea in a moment.
I imagine the Japanese would be spurred into action by an American DoW, bit I can see the rationale behind that. What would the Americans be able to use “to hand” in the Pacific? I take it German New Guinea would be the target? They’d have to move quickly to beat the Japanese to the punch.
Whatever army is based in the Philippine Islands and the East Asia squadron plus the ancestor of Fleet Marine Force and the antecedent to PACFLT, the west coast squadron. The thing is, Teddy is sneaky. Remember how Spain found out she was at war with the US? Declaration of War 25 April and Dewey shows up 1 May and shoots Manila Bay up. The Japanese will have to move incredibly fast, cause Teddy had the Dewey expedition set up for at least 3 months in advance of the declaration of war. The Spaniards knew something was fishy with all the US traffic in the South China Sea and Dewey getting more ships and ammunition supplies, etc., but surprise was still accomplished.
Now imagine Teddy's targets and where his forces are. Between Japan and the German possessions, (Philippine Islands) with battle hardened veterans of the Filipino American war in the American island garrisons.
The Americans nutcracker from Hawaii, Guam, Wake and the Philippine Islands. About 25,000 troops and 2 surface action groups. First target, the Mariana Islands, then the Carolines, and the Marshalls. Finally German New Guinea and the northwestern Solomons. Chief targets are Rabaul and Chu'uk as fleet anchorages. Hatachahcha. Japan is screwed. So is Germany, but I digress. Makes for an interesting future WWII. Imagine PACFLT Chu'ukked instead of Pearl Harbored? (There is an obscene pun in there somewhere.).
I hadn’t considered aid to Russia.
Whatever hurts Imperial Germany aids America's goals.
Not thrilled due to the failure, or the objectives?
See previous remarks about TR's Cuba experience, and the Filipino American War was absolutely HORRIBLE. TR regretted both, for what it cost the combatants involved. Remember, it was TR who had to explain about 4,000 American citizen soldiers killed in the Philippine Islands, for it was his administration that fought that war, as well as answer criticism about some of the atrocities the Americans committed to break the Filipino national war of liberation. It is a dark dark dark part of American history that is not taught too well. Just how horrible? PM me.
So no chance of the rumoured American Middle East Mandate coming off under Teddy? An American protectorate over Jerusalem wouldn’t appeal?
I would hope not. Teddy might be an adventurer and a romantic, but he was not a goddamned fool like Woodrow Wilson. Morocco was a near misstep he made and one hopes he learned from that mistake.
