But UK has very similar 3 way split (Royalty is a fourth part to it but technically comes under Executive though has often tended to work with Parliament especially since the French Revolution scared the Royals).
The system in Ireland, based in the British as is the American, is the 3 way split and again worjs far more cohesively than America's.
The literal Christian values I am talking literal meaning even if a Brit is agnostic and in Parliament or an Irishman is, their ethos is ti work with other departments actively.
Now as you see the systems elsewhere in Europe it doesn't matter how the split is, they genuinely play fairer. I am not pretending it. It just is true. It is because Christianity is so deeply ingrained into them that it is a totally different vibe and different level of rivalry between most. However, directy oppoosed parties andnsuch di play dirty but again the system is setup so that your Q anon etc stuff doesn't work in Europe as valid attacks on a candidate without proof.
