The Helsinki Final Act, signed by 35 states, including United States, United Kingdom, France, Belgium, Germany, Italy, Vatican, and what was Soviet Union and Yugoslavia back in 1975 stresses in the clear-cut terms that participating states:
- [...] will respect each other's sovereign equality and individuality as well as all the rights inherent in and encompassed by its sovereignty, including in particular the right of every State to juridical equality, to territorial integrity and to freedom and political independence [...] They consider that their frontiers can be changed, in accordance with international law, by peaceful means and by agreement.
- [...] will refrain [...] from the threat or use of force against the territorial integrity or political independence of any State, or in any other manner inconsistent with the purposes of the United Nations and with the present Declaration. No consideration may be invoked to serve to warrant resort to the threat or use of force in contravention of this principle [...]
- [...] they will refrain from any manifestation of force for the purpose of inducing another participating State to renounce the full exercise of its sovereign rights.....Byzantine Sacred Art
