I advocate round-robin test cricket being compulsory for all nations attending the Olympics. With 180+ nations playing, allowing two rest days between the five-day games, this would take almost four years. Hence the games would have to run this long.
Since there is supposed to be a truce when the Olympics are on, this would enforce world peace. In the name of the bat and the ball and the holy bails, let it be so.
