Israel doesnt care about its reputation damage. Those who support Israel will continue to support them no matter what. The only way to deal with Israel is to beat them on the battlefield or boycott their products lol. They are basically giving a free pass to do whatever. All the empty talk from the Arab world don't mean a thing to Israelis.Israel usually does things which can be sanitized or even glorified by the Zionist media. Even when it kills hundreds of people, it dismisses them as collateral damage because military opponents were using them as human shields. The Zionist media dutifully promotes the Israel narrative. On rare cases when Israel's actions cannot be sanitized away, Holocaust documentaries and WW2 movies flood the media airwaves.
A biological attack is impossible to sanitize away.
