-- No reparations whatsoever, and no war guilt assigned. The entire war, essentially, to be regarded as a tragic folly, never to be repeated. (My reasoning is that opening the door for reparations at all will inevitably lead to "
But they did this! And they did that! And, and, and...!" -- which means you'll never get that can of worms closed again.)
-- Wilhelm II to abdicate in favour of his son, but the Kaiserreich to otherwise remain politically extant. Keeping the Kaiserreich helps the continuation of stable government, and aids the wider goal of not singling out Germany as the "villain" (because in reality,
everybody rushed into the senseless war). Stability of government, combined with not humiliating Germany and not ruining it economically, will be key to preventing communist and national-socialist radicalism from gaining ground.
-- Karl to remain as King of Austria.
-- Pleibiscites on a municipal basis, to get as close to actual ethnically-sound borders as one can get. No quasi-arbitrary lines drawn on maps. Do ensure reasonable territorial contiguity. No weird exclaves, that's asking for trouble. (I do
not favour an exception for South Tirol. It must be allowed to stay with Austria, since Italy has no reasonable claim to it at all.)
-- Although it's harsh and no doubt unpopular: forcibly relocate people to their own homeland where it seems necessary to prevent prior bloodshed. All Hungarians sent to Hungary, all Romanians, Slovaks etc.
out of Hungary. Similarly, all Germans out of Poland, all Poles out of Germany. The goal of this is to prevent a future conflict by
drawing clear lines. If there's just no Hungarians on one side of a certain line, and no Romanians on the other side, then irridentism just becomes a LOT less viable. Same goes for Germans and Poles. (When the ethnic groups in question hate each other with a passion, separating them really
is the best. What else can you do? Let the cycle of slaughter and bitter resentment go on? A clean separation prevents future bloodshed, and then relations can gradually normalise.)
-- On that note: no Polish Corridor debacle. Either let Germany keep a coastal strip (inluding Danzig) to connect directly to East Prussia,
or expel every single German out of East Prussia and give the whole region to Poland. Either is cruel, but you have to pick one. Settle the matter for good.
-- Likewise, settle the Transylvanian question. Either Hungary gets a strip that connects Hungary proper to the Székely Land (with all Romanians expelled therefrom),
or all Hungarians get expelled from Székely Land and the whole region goes to Romania. Again, either option is cruel, but a choice must be made.
-- Independent Chzechia / Bohemia-Moravia (
without the Sudetenland, which will vote to join Germany and/or Austria). Similarly independent Slovakia. No artificial Czecho-Slovakian union, which was always going to have issues.
-- No prohibition of German-Austrian unification, but clear stipulation that if it ever happens, it must be via a pleibiscite, with proper procedures and democratic standards well-defined.
-- Definitely no Yugoslavia. Independent Slovenia, Croatia and Serbia. Bosnian Muslims to be thrown under the bus. Serbian/Croatian population transfers where needed, and a definitive border settled upon. Albanians to be expelled from Kosovo, which is to go to Serbia. Montenegro likewise to be included in Serbia. Macedon to be subject to municipal pleibiscites to see what its population wants.
-- Greece to be given its OTL gains in perpetuity, including annexation of the "international zone" around the Sea of Marmara. See
this map. The islands held by Italy in OTL also to go to Greece, as well as Cyprus. All Turks to be expelled from all these regions. Greeks, in turn, to be expelled from truncated Turkey.
-- Largest
reasonable Armenian state to be created, with Turks and Kurds to be expelled from its confines.
-- Kurdistan (all contiguous Kurdish-majority regions), otherwise, to be handed over to Persia. Turks, Armenians, Arabs etc. to be expelled. Subsequently, Greater Persia to become a valued member of the League of Nations, which will help to hem in the communists.
-- Sunni Arab regions to become one great kingdom under the Hashemites, with LoN backing. Shi'a majority regions, however, to become separate states. Population transfers to be carried out where this would improve stability.
-- Christians in Lebanon to receive a separate state (a mostly coastal region, from Tyre to Tripoli), with others expelled from its confines.
-- Shi'a Muslims in South Lebanon to receive a small state, reaching from just South of Tyre to just North of Haifa, and in the East stretching to include Al-Khalisa (which in OTL became Kiryat Shmona) and touching the North-western coast of Lake Tiberias. Others to be expelled from this region.
-- An Alawite state to be establihed, covering the coastal region from just North of Tripoli to the Turkish border.
-- Potentially, a Druze state and an Assyrian Christian state to be established. (If this is not feasible, these areas to become autonomous regions within Hashemite Arabia and Greater Persia, respectively.)
-- "Syria Palaestina" (essentially the square region Haifa - Lake Tiberias - Dead Sea - Gaza) to become a cosmopolitan Free State accessible to multiple religions, and to be fully neutral by treaty.
-- The Sinai Pensinsula and the Suez Canal region to become a directly administred LoN territory, through which citizens of LoN member states may travel freely for peaceful purposes.
-- All European nations to join in a diplomatic and economic union (a proto-EEC), which should ideally commit itself to sound currency and responsible fiscal policy, to sustainably restore the global economy after the war. Free trade to be established within the bloc; all internal customs duties (and other trade barriers) to be abolished.
-- All European nations, as well as the USA, to join the League of Nations, with no reservations. Full commitment.
-- LoN to adopt a stipulation that if one member ever declares war on another member, the aggressor is automatically expelled, and is understood as having declared war on
all members of the LoN.
-- LoN to adopt a stipulation that an attack on one member is an attack on all; that
all LoN members will blockade and embargo any nation that is at war with
any Lon member; that no separate peace with any enemy may ever be considered.
-- Communist nations to be explicitly banned from membership; all communist regimes to be declared inherently illegitimate; all communist states to be economically blockaded and embargoed, with no exceptions.
-- LoN to commit to defeating the Bolshevik regime. Strictest possible injunctions against any member trying for a separate peace (or any other agreement) with the USSR. Recognition of the Tsarists in exile as the "true Russian government".
-- Aggressive support for non-Bolshevik states on the Russian periphery, e.g. the Caucasian republics, Turkestan, Finland (to be supported in claiming as much of Karelia as possible), the Baltic states, Poland, Belarus (to be carved off Russia if possible), Ukraine (to be carved off Russia if possible). All these states to be inducted into the LoN.
-- Western expeditionary forces to be dedicated first and foremost to occupying and holding Arkhangelsk and the Russian Far East, with the aim of denying the USSR any practical sea access. Combined with the aforementioned peripheral states, this will box the USSR in quite effectively.
