I am merely suggesting that the quote by Moiraine "shall slay his people with the sword of peace, and destroy them with the leaf," has not been fulfilled in its entirety. I thought the wording from Sanderson, that something that took place in the first few books that is small but has big consequences would be that one event. I feel that, perchance, the Aiel might revert back to the way of the leaf perhaps in mass numbers, as in, entire clans turning into gai'shan, or that something might happen due to the non-fulfillment of this passage.

Surely it cannot be just fighting the way that they are for they are hardly taking substantial damage throughout Randland, except at Dumai's Wells.

Further, you stated that "It seems to me that this same moment may also serve for counting as the "slay his people with the sword of peace and that the "sword" here might symbolize the extra insult faced by the Aiel.
