Historicity - Different parts of the world have developed idiosyncratic cultures and languages which define that nation and all artificial nationalist designations are subordinate to that. Pride in one’s historicity and ethnicity is a fine thing, even though it will eventually be redefined by immigration;
States’ rights – There is endless fragmentation of geographical areas down to the smallest district but for defense and administrative purposes, most people are happy to own themselves part of a state not so large that it cannot respond to their needs and it can be part of a loose confederacy for defence purposes, e.g. NATO. The principle of constitutionally combining under the auspices of a larger entity, e.g. the EU, is anathema;
States are subject to their people and not vice-versa - They need to be driven by an altruistic code towards that people. They take care of welfare for those who can convince a panel of doctors and JPs that they’re incapable and they combine with other states of the same ethnicity and/or views for the purposes of defence. Their major purpose is to oppose organized coercion, either military, religious or criminal and to ensure free trade. They supply and ensure electricity and water and that’s it;
The business of states is business - Free trade is the only criterion by which disputes are resolved and the only ensurer of personal freedoms. Anti-cabal legislation is the only coercive power invested in the state. Defence and balance of power is the only justifiable usage of state militias, within the state’s borders. International dispute is resolved through free trade principles;
Appointment, tenure and promotion - To any state office, this should be according to merit, tempered by the demonstrated time period of good service.
Borders should be fuzzy - Everyone knows where historical national borders basically are and while one can dispute Schleswig-Holstein or Sud-Tyrol ad infinitum, beyond that it’s generally recognized where the boundaries are and they are sacrosanct. Therefore invading Russia is right out and vice-versa;
Understanding the cabals – Once we recognize there is an evil actively at work in high places [Ephesians 6:12], attempting to overturn the natural order, clearly spelt out in both scripture and in history and which follows the principles of reduction of and enslavement of the common man under a global elite, ordering and regulation of all aspects of life, destruction of the family and suppression of religious belief, reduction of the world population to eliminate inferior species, promotion of deviance in all aspects of life and the rule of the world under a cabal of cabals, itself ruled by a certain shady entity, then all the other aspects above become infinitely stronger and more easy to maintain.
Having said all that - Each home country in the British Isles has its own parliament, which in turn cedes certain powers to local government; the national assembly meets on the Isle of Man for strategic and defence purposes only.
