Ben Shapiro should debate Nick Fuentes. I believe Shapiro's strongest arguments would be that, without policing (whether by Israel or another force), the area would be overrun by terrorists, and that buildings were leveled to prevent military casualties during operations to clear structures rigged with IEDs.
Furthermore, it should go without saying that not everyone skeptical of Mossad, the Israeli government, or Netanyahu is anti-Semitic. Israel is frequently involved in global controversies, a situation that could be attributed to its geography and a self-fulfilling prophecy stemming from a persecution complex. This complex is understandable, rooted in a long history of Jewish persecution, with the Holocaust being the most notable and recent example. This frequency naturally makes Israel a "person of interest," meaning it is not necessarily guilty of anything but is always part of the discussion. AIPAC is another significant factor fueling skepticism, and this would need to be addressed for the pro-Israel side to build public trust.
P.S. The situation in Israel appears to be ethnic cleansing to me, which I find unacceptable. I acknowledge that I could be swayed by propaganda or the dominant views within non-mainstream political circles, but thus far, Israel does not appear trustworthy.
