Spirit of the Sixties,
What do you find objectionable about the short lesson on the origins and working of the power structure of the UN? The Security Council may be elitist and it often is disfunctional, but perhaps the intent was to put checks and balances in place.
Do not forget that when the UN was established, much, perhaps the majority, of the current membership that sit in the General Assembly were still colonies. Thus there was an imbalance in the General Assembly, with the western democracies outnumbering what would become the Soviet Bloc. As a result, a number of member republics of the USSR were granted seats in that body as a counter balance.
I am old enough to remember the Soviets boycotting the Security Council and being caught flat-footed when the resolution on Korea passed. As the time it was recognized as a major error on their part, due to, well, I'll let others more better qualified debate their motivation.
Regards
