I don't know when the OP is returning, (s)he has not posted in this thread since it's creation on the 26th and their stats say they have not been seen for 2 days! I will wait till friday to get a response/go ahead for introducing my POD. If nothing else, I'll just post a DBWI thread on friday, and in that thread I'll introduce my POD. Everyone is jammed up on a POD that has the USA being in the Central Powers in/by Aug, 1914. If folks want to discuss a planned departure from OTL, with years of changes before hand, then that changes things a great deal, and makes it very hard to have a meaningful discussion when we don't know how to get from OTL to ATL.
That said, my POD begins in late 1913, but doesn't change any diplomatic relations, military forces, military forces deployments, military budgets, or really anything other than setting the stage for the important change, that gives us an unsuspecting USA getting into the CP (by default --- against her will and intentions), and cycles from OTL to ATL in 60 days. As this may not be what folks want in this thread, I'm not going to post it here without the OP's giving me the OK. I shared my POD with a small group on friday, including the OP, but have not heard from the OP yet, either in a PM or by response here in thread, so...
I'll say this, in WWII the USA had the Panay incident, the reaction too which was like "Meph" and then there was Pearl Harbor. One of the folks I did share this POD with proposed a change that would (IMO) make it a Panay type thing, while my version would be more like Pearl Harbor. The nice thing about this thread is it challenges us to examine an alternate WWI where (somehow) the USA is both in the war, and on the wrong side, right from the beginning of the war! WWII tells us what it took then to get the USA into the war, and so we have the dilemma of either years of gradual changed circumstances, and all the butterflies that these changes unleash, or a sudden, dramatic change brought about by {something} that drags the USA into the mix, without the need to change a thing.
Will my POD give us an excuse to have such a world/discussion, I believe so, but then we will have a starting point that may or may not be what the OP had in mind.
