You know, I am only answering this question because my answer can be pretty short. You know a lot more than I did and seem to have answered your own question? Britain of course famously removed itself from the Roman Catholic Church so King What's His Name could divorce his wife, hence the Anglican Church. The British Empire included what would become the USA, Ireland, parts of the Carribean, India, Hong Kong< Singapore, Maylasia, Africa, Canada, many African countries, Australia, New Zealand, Iraq was made up after the petroleum revolution. Northern Ireland we all know is part of UK, only the Southern area is the soveriegn nation of Ireland. China remained unconquerd despite the ravages of the opium attacks, Japan viciously repelled them after seeing what happened to the rest of the neighborhood. Britain might not have a friend in the world were it not for BBC news and the support of its religious humanitarian missions.
Anyway, Ireland was not just another colony. Ruthless landlords and other miscreants could hop a ferry and do their worst with the backing of Crown military, and like the Indians of the USA, taditional language, dances, music and other cultural touchstones were brutally supressed. In WWII the Irish did not care for Hitler so much, but why bother with sympathy for the Brits, really?
Well, enuf said. Tony Blair was an apologist for Clinton's global *****-up, Thatcher followed our colossal jackass Reagan to the disgrace of both nations and now the UK stands by the US perpetually much as a poodle stands by it's owner so banksters have some hope of getting away with grand theft along with their Yankee counterparts. The Orange Men and others reamain as points of pain. Perhaps, as with the American Civil War, the worst will be forgotten one person at a time.
