The Bitter Peace
Conditions that must be satisfied to trigger bitter peace:
* Germany controls Paris.
* Germany is not at war with Italy and Japan.
* Do not sign the Tripartite pact with Japan if you intend to attack the USSR without them. Just sign it with Italy.
* Soviet does not control these provinces:
o Leningrad (one of the northern provinces, very close to Finland)
o Moscow
o Stalingrad
o Baku (southern province, next to Persia)
o Sverdlovsk (in Trans-Siberia railway, quite far away)
If you fulfill those conditions, there is 5% chance every week that Stalin may sue for peace. When the event triggers, there is 90% chance USSR will surrender and Germany will obtain a large amount of provinces. Unfortunately if Soviet refuses, the war goes on and you may need to annex USSR to claim victory. The refusal message is: Soviet Union went with Fight to the bitter end! in Sue for peace with the Germans
There are two Bitter Peace chains, one with Japan in the Axis and one without.
* Without the Tripartite pact being signed by Japan and without Japan in the Axis, # Sue for peace with the Germans, event 2624 SOV starts the event chain which is completed by the Germans accepting it: event 2024 GER # Stalin sues for Peace (Japan is not Axis).
* Providing Japan is in the Axis (and at war with Soviet), Sverdlovsk is not required. But Soviet must lose Vladivostok (next to Japan's Korea). Event 2645 SOV which triggers event 2046 GER
* There is a third and somewhat unusual Bitter Peace if you are not at war with the Allies (UK, France and USA), you only need to conquer 25% of the Soviet national provinces (note that Eastern Poland provinces are not Soviet's national provinces).
The Bitter Peace in Doomsday
The ideas are generally the same, but there are some significant differences in Doomsday:
1) The Tripartite Pact is now irrelevant. Offer it to both Japan and Italy since there are no Bitter Peace problems.
2) If Japan is Axis or fighting the Soviet Union, the 5th Russian province can be either Sverdlovsk or Vladivostok. The other 4 needed Russian provinces remain Baku, Leningrad, Moscow, and Stalingrad, and either Germany or Vichy France has to own Paris.
3) The AI has to accept the Bitter Peace, there's now a 100% chance of the AI accepting the Bitter Peace once it fires.
4) The % chance for the event to fire has been increased to random = 35 meaning that it should fire in 3 or 4 weeks, but there is no guarantee that it will fire, just a much increased chance that it will fire. Also the time interval between checks has been changed from every 7 days to every 10 days.
5) Other conditions such as Paris not being controlled by France are still the same. Either Germany or Vichy must control Paris.
