Deathstalker wrote:To add the WWI discussion, England was living on borrowed time itself as far as starvation. Britain was losing merchant ships hand over fist to U boats, and if I recall, no one knew how bad it was and by the time they realized they were out of merchant ships, it would be to late. Another year of war, without US ships to help convoys, may have Britain reach a starvation point before the Germans. And the Germans could always buy or bully a continental power for food and have it delivered by rail.
The basic presumption is that unrestricted submarine warfare and US entry on the CP side are mutually exclusive. The OA (original assumption) was that the US joined the CP because the Brits were killing Americans smuggling goods to the CP. That's a very unlikely OA I admit but if that truly was the situation, an unrestricted submarine campaign would throw the US to the entente.
On a more basic level, the U-boat threat to the UK was not causing it to "live on borrowed time". It caused a crisis certainly but British countermeasures, most notably the introduction of convoying and the construction of specialized ASW escorts brought the situation under control. In fact, by 1918, the RN actually had greater operational expertise in ASW - and better equipment - than it did in 1939 (yes, the loss of expertise was that great). For example, in 1918, British ASW ships were using towed arrays and had SOSUS-like underwater sensors. The unrestricted U-boat campaign failed.
Reparations
Are out. The US wouldn't pay them and the Entente had no means of forcing them to do so. I believe the "Sorry about that" peace treaty is the most likely result. Basically everybody agrees to pretend the US declaration of war in 1917 never happened and everything that stemmed from it was a delusion caused by swilling too much cognac at a diplomatic reception. It's the simplest way out for everybody.
With the cost of sustaining another two years of war without the support of the United States, Stuart? I don't think so; the size of the lost generation will be much larger, and the industry of the country strained to the breaking point.
Agreed, no argument there either. However, a lot of assets in the UK did actually exist. (Lloyd George refused to deploy them to France, officially to prevent Haig launching more offensives, actually as part of his personal vendetta against Haig. So, there is capital that can be run down to push Germany out of the war. A competent allied strategic looking at the situation will see the CP are now split into two sections with the Atlantic between them. Germany is dying on the ropes and nothing can save it short of a miracle. So, the grand strategy would be to knock Germany out of the war quickly before America can properly mobilize and then either strike a deal with the United States or fight the war there. preferably the former. Note that this is a neat reversal of the actual strategic situation that existed at the start of 1918 on both geographical and political/operational terms. The big difference is that Germany was dying then. It took everything they had to trhow their 1918 offensives in 9including troops from Russia) and, hyperbole apart, they really didn't get very far. So, I would expect that with American-supplied munitions and manpower replaced by drawing down stocks in the UK, the rest of 1918 would follow much along the same lines. The truth of the German collapse is that it was largely the British Army 'ere what done the deadly deed (cockney phrasing deliberate). The French did much but the US was more or less along for the ride (something acerbically noted by British field commanders).
Germany might hold on a bit longer in the hope of an American rescue but there won't be much in it and any delay will simply make matters worse for them. Best case, they collapse on OTL schedule and get the Versailles treaty less the Wilsonian nonsense of League of Nations and so on. Worst case, they anger the Entente so much they get a much worse peace deal, essentially the four-states solution I described.
That would leave the United States out on a limb. It's going to be 1920 at least before their forces are capable of tackling the Entente. Looking at historical ship commissioning rates, the US will add to its fleet
Mississippi in early 1918,
Idaho in mid-1918,
New Mexico in mid-1919,
Tennessee in mid-1920,
California in mid-1921,
Maryland in mid-1921,
Colorado in early 1923 and
West Virginia in late 1923.
Washington would have been completed in late 1924. Even being very generous, that means the US battleline would have been increased by eight battleships by 1924
six years after the defeat of Germany. Assuming the Royal Navy finished the four Hoods in by the end of that time period (Hood was completed in early 1920 so I don;t think that's unreasonable), the balance becomes 22 US battleships versus 31 British battleships and 13 battlecruisers (plus the three Courageous class ships which defy sane classification).
So, where do we go from there? Well, the next major US building program was the six South Dakota class battleships that were expected to enter the fleet between 1925 and 1927. They were followed by the six Lexington class battlecruisers that were expected to joint the fleet between 1927 and 1929 (probably two per year in 1927, 1928 and 1929). These were a serious priority for the US Navy. In that period, the British would have built the four G3s (at least). technically they are battlecruisers but they were really fast battleships.
So, by 1930, the balance would be 28 US battleships and 6 battlecruisers vs 35 British battleships and 13 battlecruisers. On this trendline it would be the mid-1930s before the US battleline was capable of matching the British - and even then it would be running at a speed deficit. In fact, I'd guess that a lot of older ships, expecially the 12-inch ships, would have gone by then. This would be 16 years after Germany went bye-bye and I honestly can't see the US continuing with a phony war for nebulous causes for that long. I think that, around 1920, there would have been the "sorry about that" peace treaty and everybody would have packed up and gone home.
The Europe that was left would make an interesting history tale though. A largely peaceful Europe with Germany split up between four seperate states with "German nationalism" discredited by the crushing defeat in 1918. No WW2 in the offing for reasons we discussed earlier. That would be a really interesting situation, a big charge from the familiar "who won WW2" to the new "no WW2". That's really alternate.
