The Budapest memorandum and the Istanbul document are two important documents thought to guarantee security & stability in the regions of the former Soviet Union. 1
The Instanbul documents states:
"We reaffirm the inherent right of each and every participating State to be free to choose or change its security arrangements, including treaties of alliance, as they evolve. "
I have heard that the Instanbul document is a declaration of intent, not a treaty. What is the legal character of this document? Is it legally binding? If yes has Russia retreated from that agreement?
