Edit: Thanks go to ApparentlyImAHeretic for the correction. I made a mistake, the above article is not regarding this statement (It uses similar titles so I made an error of judgement). The original statement can be found here: https://www.maariv.co.il/news/politics/Article-1071561

You will need to translate it which you can do easily through Google.
