International law deals almost-exclusively with nations.
For instance, I have filed an application against my country in front of the European Court of Human Rights (ECHR). But, I cannot file an application against any persons who have committed criminal offenses against me in front of that body. It is only possible to sue a state.
At the International Criminal Tribunal for the former Yugoslavia (ICTY), they only try e. g. generals.
Bodies of the United Nations (UN) act at national, ethnic, or similar and not personal levels.
International laws are contracts between nations. Any non-national military is "paramilitary" to them.
For instance, the Convention for the Protection of Human Rights and Fundamental Freedoms according to which the European Court of Human Rights (ECHR) judges is a contract signed between all member states. You might call this court an arbitration body.
These courts are different from national courts in the sense that they apply only to states which adhere to them. For instance, the United Nations (UN) cannot apply a single United Nations resolution against Vatican City as it is not a member of the United Nations (UN).
Libertarianism is already global, but is valid only for entire states.
What sort of application did you file against your country? What country is it?
