::You explanation is confused and I couldn't understand. If you were right, why would USA and Soviet Union not to be listed in Six Day War's list of combatants since both the Isareli and the Arabs was heavily aided by them? The USA was a combatant in Vietnam War but it didn't mean that they fought in every battle.
