If you watch Peter Beinart's channel, he has had Ehud Olmert and Avraham Berg on. IDK if they touched upon starvation specifically, but it seemed like they were not in denial about Israel's actions, especially the latter (I think Beinart lightly pressed Olmert on whether Israel's actions constitute genocide, and Olmert disagreed, and I don't know that I begrudge him that, given his position).

Neither of these former politicians are current leaders, of course.
