This organ, the United Kingdom National Security Apparatus (UKNSA), will include committees representing various organizations that were responsible for safeguarding Great Britain’s security in 1918. Set directly after the end of the Great War, delegates in this organ will likely face both internal and external crises, including but not limited to unrest in Ireland, the rise of communism in Great Britain, the United Kingdom’s place in the international system, growing discontent in the British colonies, and the needs for systemic domestic reform. Delegates from the United Kingdom’s Cabinet, Royal Irish Constabulary (RIC), and the British Secret Intelligence Service (BSIS) will be able to communicate between committees, while actions taken by the Irish Republican Army will be able to affect events in the other committees (though delegates will not be able to communicate outside of their committee). Finally, the British House of Commons will work along a similar timeline to create and pass legislation related to the topics covered by the rest of the organ, but will not have crisis elements.
