On pages 59-61, one would find an interesting tidbit: US President Roosevelt advised that when countries involved in a conflict should not vote in related resolutions. To explain, if the Brazil was in the SC and found itself in a quarrel with the United Kingdom, then both parties could not vote in resolutions that attempted to end the problem.
And more daringly, the veto power to stop the resolution could not be used!
Perhaps unfortunately, the veto right restriction was not exercised. That more than most other reasons crippled the United Nations (UN).
Another tidbit was that the Soviet Union actually proposed a UN led international airforce that would respond to global incidents! Great to explore further : )
