The "note" s/he left was a demand for intervention for his/her side. S/he was not asking for neutral mediation, that much is clear, and you shouldn't make little of that - it only arouses my suspicions that your intervention wouldn't be a neutral one. As for your question, I read your infobox and the categories on your profile about Israel and got mixed up. About my asking the WikiProject Palestine people to not intervene: well, no one has intervened from that corner thus far - they probably know the Wikipedia rules better than I do, though, yes, I think it's absolutely necessary that people from other political persuasions provide balance in the conversation if Precision123's own canvassing succeeds.
