It is not necessarily a centrist position, it is the only realistic solution so far proposed. Every other proposal known to me stands no chance at ending hostilities, hatred and oppression. At least if one is not willing to commit genocide or institute a permanent state of apartheid. Peace achieved by the total destruction of the opposing side unfortunately appears to be something some few influenceal people on both sides apparently see as acceptable or even preferable. These individuals must be removed, before peace can be achieved. The solution I would prefer would be that of a federated, strongly decentralized state containing both Israel and Palestinian lands, to allow both groups secure, orderly and mutually recognized access to their respective and their shared heritage, communities and their homes. Unfortunately this appears impossible in the current situation and has always been an incredibly ambitious plan, but perhaps it can be achieved at a later time, when the conflict has ceased for some time and mutual understanding and respect have been established.
