The NGOs have 60 days to provide the information that Israel ask for and here's a prediction for what the "international community" will do if they refuse and get de-registered: nothing. It's just more empty words.
If you struggle to understand why, then it's because what Israel is asking for does not seem that unreasonable to anyone that doesn't already hate them.
Despite Oxfam calling the new rules "arbitrary" a less biased outlook would understand why Israel wouldn't want to continue working with organisations that employ staff openly hostile to them. Grounds for rejection include:
Denying the existence of Israel as a Jewish and democratic state
Denying the Holocaust or the Hamas-led attacks on Israel on 7 October 2023
Supporting an armed struggle against Israel by an enemy state or terrorist organisation
Promoting "delegitimisation campaigns" against Israel
Calling for a boycott of Israel or committing to participate in one
Supporting the prosecution of Israeli security forces in foreign or international courts
From the BBC: Israeli military body Cogat, which controls Gaza's crossings and co-ordinates aid deliveries, meanwhile said the INGOs facing suspension "did not bring aid into Gaza throughout the current ceasefire", which began 11 weeks ago. It added that "even in the past their combined contribution amounted to only about 1% of the total aid volume".
The diaspora affairs ministry said the primary reason INGOs had their licences revoked was "the refusal to provide complete and verifiable information regarding their employees," which it said was critical to preventing "the infiltration of terrorist operatives into humanitarian structures".
Fewer than 15% of the INGOs providing humanitarian assistance to Gaza were found to be in violation of the new regulatory framework, it added.
