Netanyahu has made it quite clear that his goal is the end of Palestine as a sovereign state. Quoted in the "Times of Israel" publication as saying:
“in any future arrangement, or in the absence of an arrangement,” he said, Israel must maintain “security control” of all territory west of the Jordan River — meaning, Israel, the West Bank and Gaza. “That is a vital condition.”
He acknowledged that this “contradicts the idea of sovereignty [for the Palestinians]."
Seeing as part of the definition of Genocide is to:
destroy, in whole or in part, a national, ethnical, racial or religious group
I would argue that falls under the definition as outlined by the 1948 Genocide Convention. Your focus on total eradication of people and culture is only a part of the definition of genocide. Also, they are certainly doing an unnecessary amount of eradication of Palestinians and their culture, regardless of if it is an "expressed intent".
Lastly, "plausible" doesn't mean "just run with it", but I never said it did. Plausible means "plausible". As in, your argument that it "definitely isn't genocide" is directly contradicted by the ICJ ruling. People whose judgement the world put their faith in to make the distinction couldn't definitively say it wasn't occurring given the information they were given access to.
Edit: need to add some clarity. It's not simply that Israel plans to end the nation state of Palestine. They are intending to end Palestinians as a National Group. This has been made clear by retorhic such as posted in this comment, as well as Israeli President Isaac Herzog’s statement during an Oct. 13 press conference. In his statement, Herzog said, “It’s an entire nation that is out there that’s responsible. It’s not true, this rhetoric about civilians not aware, not involved. It’s absolutely not true,”.
Beyond that, according to Raz Segal, the program director of genocide studies at Stockton University:
Israeli forces are completing three genocidal acts, including, “killing, causing serious bodily harm, and measures calculated to bring about the destruction of the group.” He points to the mass levels of destruction and total siege of basic necessities—like water, food, fuel, and medical supplies—as evidence.
