I think part of what the UN does is to make it very difficult for anyone to intervene in anyone else's business out of ethical concerns without facing a discourse of submission to authority of sovereignty. In other words, the first thing UN agents do is attempt to preserve sovereignty as long as possible as war-avoidance. Cultural relativism and moral relativism are held as reasons that no one should interfere in the affairs of someone else with "a different culture." The fact is that defining cultural differences and boundaries is itself a relativist power-claim, and there is no reason why national-state authorities should be able to define culture for individual citizens and therefore claim special jurisdiction over intervention in their affairs. Granted, any authority should operate in dialogue with the authority of whosever affairs it is intervening in, but this must occur at the individual level, imo.
The UN has strictly outlined procedures for when intervention is allowable and recognizes the sovereignty of nations. It will not impede the right of any national entity to make its own choices and is not allowed to hold any nation to its own standard of decency through force unless absolutely necessary.
This language assumes that collective self-determination is ontologically possible. I dissect collectivist language-claims and always find that collectivism involves some individuals being subjugated to the will or interests of others. A "national-entity" can't make "its own choices" because "it" doesn't exist except as conflicting interests and individuals. Why should individuals be subject to exclusion from interaction with other individuals on the basis of statism? If one individual is defined as having the same nationality as another, she is free to intervene in the other's affairs but if they are defined as having different nationalities, it can be called an act of war? What kind of nonsense is that?
Collectivist action is a different story. If multiple individuals coordinate their actions to exercise oppressive force over others, shouldn't that be checked, regardless of whether the individuals are defined as having the same or different nationality from the people they are attacking?
Recognition of sovereignty is not consent to allow any manner of atrocity.
Maybe not, but it is itself the means to allow the atrocity of discrimination on the basis of national citizenship.
Due Process is found in the 14th Amendment. It also does not define due process. The courts have been interpreting the exact extent of due process for over a century. Even the federal government before the fourteenth amendment was not held to the same standard of due process that we have today. Civilizations evolve.
I'm afraid that informal trial and punishment occur in various forms regularly and pass as everyday affairs. Employers can investigate and punish or fire employees without due process or even explicit notification. Managers just base their decision on one thing and give a different reason for disciplinary action. Look at media scandals. Was Tiger Woods given the privilege of due process or rights of the accused? No, he was simply subject to public humiliation protected by freedom of speech. I'm not arguing against freedom of speech, of course, just pointing out that people still find informal ways of exercising pre-modern power tactics without giving much thought to the fact that they are acting as judge, jury, and disciplinary agent.
Nor is recognition of sovereignty consent to allow dictatorship.
Note that political and philosophical forces led to the eventual institution of a nation standard of rights.
What is sovereignty except a form of dictatorship?
I can look for sources and cite them later if you like (I need some sleep) but it is the historical reasoning that these limitations on states were to form a more cohesive union. Many of them address issues specific to the failure of the Confederate States. Individual states would print bank notes that were more or less valuable depending upon which state you were in and some would not accept any other currency. The states levied variable taxes and tariffs on one another to reduce out of state competition or just to turn a profit. States would invalidate contracts from out of state lenders to free its citizens of their obligation to consideration.
I suppose standardizing currency can be called a form of cohesion. It can also just be called a convenience for market exchanges. Appropriating governmental institutions for business discrimination is corruption, not incohesion. All of these things sound like abuses of power the way you describe them, but I'm sure their are situations in which they would be a lesser evil of necessary evil to check/balance some other act of corruption. It's always handy for one side to point out the ethics abuses of the other as part of a discourse to claim legitimacy and redress. In reality, democracy like war usually involves some level of ethical shortfalls on the part of both sides. The only hope is de-escalation since allowing them to subject each other to political accountability only adds another dimension to the bickering.
I may respond more to this later. Right now I would just like to say that I am referring primarily to historical interpretation. We are in "History & Humanities" discussing the history of constitutional interpretation and its changes over time. Your posts and arguments seem to be applying a modern interpretation of constitutional principle. I am only saying that this sort of interpretation was not always in force. Realizing and understanding the history of the document, its various interpretations, and the context of its creation and amending is important to our modern perspective.
I don't think you have access to any interpretation except through the lens of your current interpretation. You may believe that you can transparently survey different interpretive frameworks as changing through time, but you seem to ignore that to interpret those frameworks, you have to interpret them from your own perspective. I'm willing to discuss reasoning and evidence that one texts exhibits one interpretive framework and another another, but I disagree that you can assume cohesion among everyone living during a particular time of how they interpreted constitutional passages or anything else. If anything is certain about interpretation, it is that there are always conflicts and dissent.
