There is no indication that Britain was going to set up anything other than a Protestant satellite like Scotland, and no sign it would happen in the foreseeable future on the eve of WWI.
We can debate this until we’re blue in the face; Britain’s continued occupation of the north of Ireland doesn’t support your contentions.
What occupation? Northern Ireland has a devolved parliament and are not ruled directly from Westminster. They have printed their own money for as long as the so-called “Republic” of Ireland has. Yet no complaints out of you for the European Union “reuniting” all of the British Isles politically under a single aegis (or as some have tried to rename them, the “Atlantic Archipelago”).
Are you going to call Canada “occupied” too? They have a Governor General and Queen Elizabeth’s face is on their currency.
I wish you’d debate with facts instead of propaganda—and the propaganda of leftists at that.
