BRITISH EVENT: With Friends Like These
Having done everything it can to mediate a resolution, London has been thoroughly embarrassed by Majterre's utter disregard for good-faith diplomacy. While nominally allied through the marriage of Harry and Artemis, government advisors point out Britain has no formal foreign policy obligations, and with the prospect of a major war now dangling over the continent, there is considerable public support to cut all ties to the demonstrably dishonourable régime.
Annul the Marriage: Exploiting legal loopholes and circumstantial irregularities in the marriage ceremony, the British government declares Harry and Artemis are not, in fact, properly wedded, terminating the union with immediate effect. While a largely symbolic gesture of neutrality to countries not preoccupied with hereditary matchmaking, Majterre is certain to read this as a major affront and future diplomacy under the Solomon dynasty may never recover. Replace Royal marriage to the House of Solomon with Celebrity Breakup: -5 diplomacy with Majterre.
Garfield in: Royal Rescue: Conversely, Artemis may be your last recourse to turn this ship around: encouraging her to declare her mother incapable and assert her claim to the throne, London effectively backs a coup attempt in the hope she can enforce a saner government. Artemis Solomon will launch a coup attempt at turn's end with a +5 bonus to roll; replace Royal marriage to the House of Solomon with The Huntress' Coup: +3 diplomacy with, -3 casus belli v. Artemis' faction and vice versa, +4 casus belli v. aggression on Artemis, +4 to claim leadership of the rebels if Harry succeeds Artemis; +5% support for Conservatives, +3% support for Imperial Party; Majterre gains +3 casus belli v. Britain. Supporting Artemis will be read as opposing the Heretics' Crusade.
Pax Britannica: While Crete is a lost cause, you may yet be able to leverage enough influence to prevent neighbour countries from inciting a continental war, though they will consider it an enabling of Esther's bellicosity. -5% support for Labour, e350tb loses 10% approval; gain policy Misguided Mediator for 20 turns: +2 diplomacy and -2 casus belli with Majterre, -3 diplomacy with the Volksreich and European Federation; barring severe provocation, neither country will join an offensive war against Majterre for this duration.
Wait and See: It's too early to make a decisive call on foreign policy. No effect.
