I wonder what you mean by a “continuous US-led peace talk”? What would this look like in practice?
I could imagine the establishment of a platform initiated by the US to facilitate such talks. That being said, it seems to me it would be difficult to have these talks indefinitely. Also, I think a flaw in such a system could be that the US may lose its credibility (assuming it currently possesses that!) after which the negotiation platform would lose its credibility.
