Benjamin Netanyahu, the Israeli prime minister, has not yet commented on the conference, which brought together 11 ministers and 15 coalition MPs, including some from his own Likud party.
He has previously indicated that he opposes resettling Gaza after the war.
But the gathering was criticised by politicians from across the political spectrum, who warned it had exacerbated division in Israel and undermined its defence of genocide claims brought by South Africa at the International Court of Justice.
Gadi Eisenkot, a much-respected ex-chief of staff for the Israel Defense Forces (IDF) and an influential member of the war cabinet, accused those who attended of having “learnt nothing” from recent events.
“Everyone who took part in that event yesterday, and especially elected officials, learnt absolutely nothing from the events of the past year, about the importance of acting in accordance with a broad national consensus and in solidarity with Israeli society,” Lt Gen Eisenkot, whose son died fighting in Gaza last year, said.
Ya’akov Margi, the welfare and social affairs minister from the ultra-religious Right-wing party Shas, also condemned the conference.
He said it was “not the time” to talk about building settlements in Gaza while the war was still raging.
