@markhertling Strangely enough in hindsight, that was less the case with the Soviet Union. The principles in the Helsinki Final Act (of the CSCE) set the parameters for security in Europe from 1975 until 2014 or arguably later. Putin’s invasion of Crimea and more recently Ukraine tore up the agreement signed by HOSG from NATO, Warsaw Pact and European Neutrals - which was not legally binding but was observed by all.
