Ban from the next future Olympic competition the team of any country that has participated in any aspect of war making since the previous Olympic gathering.
Why is this important?
This would be congruent with the historic past when Greek city states would cease war making to gather for athletic competitions. It would empower the current Olympic Committee Members to incentivise justice and peace for governments of the world to be able to participate in Olympic Competition.
Truly ruling bodies (the International Olympic Committee) MUST use their rule making authority to promote the betterment of their constituencies, as did the track and field governing body regarding anti-doping enforcement.
