Warnings have been issued by police after thousands of people gathered in west Belfast to protest over the Northern Ireland protocol. Police estimated that more than 3,000 people took part. Under the protocol in the Brexit withdrawal agreement, designed to avoid a hard border on the island of Ireland, Northern Ireland in effect remains in the single market and EU customs policy is enforced on goods coming from mainland Britain. This year there has been loyalist violence from those who claim their British identity is being brought into question by the arrangements. Talks on resolving the impasse over the implementation of the protocol collapsed without agreement. So the Brexit Trilemma is causing considerable conflict between Britain and the EU, and also between Britain and the United States - due to PM Boris Johnson's lack of ability of restoring peace in Ireland, and his reluctance of adhering to the Northern Ireland protocol. Therefore a referendum on a united Ireland - in conjunction with a joint referendum on a united Britain-Ireland - ought to be implemented to resolve the Brexit Trilemma; as well as to end the partitioning of Ireland and making it into one entity again. Unless of course the people of the island of Ireland prefer the Status quo. However, these very important political issues can only be resolved by truly, peaceful democratic means - namely a referendum. It should also be noted, that the founding of the Republic of Ireland was paved with blood, with many innocent civilians killed by extremists in the process - the Republic of Ireland still being shaky today, intensified by the Brexit Trilemma. However, the Tudor conquest of Ireland by Henry VIII - who was declared King of Ireland in 1542 - was also paved with blood; when the polity of Gaelic Ireland was largely destroyed. So there is a bit of catching up to do, when it comes to resolving Irish-British political issues by truly peaceful democratic means - namely a referendum, on a united Ireland as well as a united Britain-Ireland. Both of these possible political solutions would have their merits. Such as ending the partitioning of Ireland and making it into one entity again; so that peace and harmony can be manifested in Ireland and Britain. To resolve the political crisis in Ireland and Britain, a referendum with three choices ought to be implemented - on a united Ireland, a united Britain-Ireland or to remain with the Status quo - so that the Brexit Trilemma can finally be resolved.
