I'm pretty sure it means "Plausibility Check".
@Eurofed:
1: It doesn't matter that much anyway, Prussia still gets the Sudeten and Saxony. I was assuming that whoever was negotiating for Prussia would know what would be too far and provoke French intervention, but it doesn't really matter.
2: This was what I was trying to say, but I wasn't clear. My apologies. This is the situation I was trying to portray.
3: If the casus belli is Rome only or Rome and Luxembourg together, then Italy might join. Otherwise, they might be cautious about attacking the premier land power in Europe, or so everyone thinks. They have just been through a major war, and their country is barely 10 years old and by no means unified. They need time to consolidate. After Sedan or an equivalent, Italy will almost certainly join for Nice, Savoy, and Corsica if they can pull it off. I can't see Prussia taking more than it did OTL, since I think France will sue for peace after Italy joins. Austria will be in no shape to join the war.
4: I think the US will stay out of a *WW1, but I think they will be fairly pro-*Entente. Yes, you have all those lobbies you mentioned, but you also have Britain as the US's largest trading partner, and the trading interests have lobbyists too. If Britain enacts a blockade of Germany, I think that relations will steadily go downhill, as OTL. This time, there will be no German USW to save relations, since Germany can get all the food it needs from Russia.
I think Austria will survive to WW1. There will be a worse version of OTL's Augsleich, but it will survive. One result might be a Triple Monarchy forming after the war with Prussia, resulting in Austria-Hungary-Bohemia.
Now, whether it survives WW1 is another question. Austria, attacked on three (or 4, if there's a Serbia in the south) sides, will fall very quickly. After that, Germany's full strength can be concentrated against France. France will take longer, but they will, most likely, fall as well. After that, it's Britain, Turkey, and Japan vs. Russia, Italy, and Germany. Turkey will fall fairly quickly, and Japan will follow before hordes of Russians start flooding into Manchuria. Britain will be forced to surrender by this point.
This scenario assumes that a lot of the events leading up to WW1, like the Russo-Japanese War, happen more or less as OTL, which is by no means assured.
