What do you know of this person? I can only assume you made this up with no knowledge of him, based on what I'm seeing. For example, according to Wikipedia:

In August 2023, Bartov was one of more than 1,500 U.S., Israeli, Jewish and Palestinian academics and public figures to sign an open letter stating that Israel operates "a regime of apartheid" in the occupied Palestinian territories and calling on U.S. Jewish groups to speak out against the occupation in Palestine.

Bartov has said that Israel's 37th government brought "a very radical shift", adding, "I am a historian of the 20th century and don't make analogies lightly" before recounting how the movement of fringe politics into the mainstream in Europe led to fascism, and emphasizing: "This is the current moment in Israel. It's terrifying to see it happening."

In January 2024, Bartov said that Israel had repeatedly expressed genocidal intent against the Palestinians in the Gaza Strip during the Gaza war. By August of that year, having visited Israel again in June, Bartov said it "was engaged in systematic war crimes, crimes against humanity and genocidal actions". On April 24, 2025, Bartov said: "It's a misnomer to call it a 'war'. [...] This is an occupation by the IDF designed to take over Gaza. There will, of course, be resistance, but it will be guerrilla resistance." He also noted the violence had escalated beyond Gaza to include the West Bank.
