Lol...so why don't the "aggrieved" parties take that case into international court?
“Lol...so why don’t the “aggrieved” parties take that case into international court?”
With respect to subject matter that is within the jurisdiction of the international courts without the cooperation of Russia, the Ukraine has initiated legal proceedings.
However, the larger issues such as the right of sovereignty over the Crimea is not subject to the jurisdiction of the relevant internatonal court/s without the Ukraine and Russia agreeing to that jurisdiction. Since Putin and Russia are not about to agree to the jurisdiction of an international court, nothing the Ukraine can do will compel Russia to submit the issue to such a court.
