Not the greatest source I shared here. But it's the same story anywhere you look up. Not enough substance in Israel claim these groups are terror organizations.
But do agree with Israel decision. For many reasons. The main reason for me is as it may pose a national security threat to Israel as these organizations could have ties with terror groups. Maybe.
If the possibility exists then one should prepare for that possibility and that's what Israel is doing labeling these Palestinian humanitarian groups as terror organizations.
