To destroy the UN agency set up to aid Palestinian refugees based solely on unproved accusations is truly waging total war. From William Van Wagenen at thecradle.co:
Tel Aviv’s goal of dismantling the UN agency in the name of security is a strategic move aimed not only at depriving Palestinian refugees of lifesaving assistance, but completely eradicating the notion that they will one day return to the lands they were expelled from.

The UN Relief and Works Agency for Palestine Refugees in the Near East (UNRWA) is facing the gravest existential crisis in its 74-year history, as funding cuts by several western countries come on top of ongoing atrocities perpetrated by Israel in Gaza.
The UN agency is unique in being the only one dedicated to a specific group of refugees in specific areas, and the only relief organization that operates a full-fledged educational system. UNRWA is also the only organization mandated to work in Gaza and distribute aid to the two million people currently trapped and starved in the besieged enclave.
To compound these challenges, the occupation wants to see it dismantled.
UNRWA must be destroyed
In January, Israel alleged that Palestinian members of UNRWA’s staff participated in the resistance’s Operation Al-Aqsa Flood on 7 October, leading the US and 18 other nations to swiftly suspend funding for the organization.
The suspensions were met with shock, as UNRWA plays a key role in providing food and medicine to starving Gazans struggling to survive Israel’s siege and bombardment of the coastal enclave.
However, Israel’s allegations are not based on any evidence. They are instead part of a classified plan prepared in advance by Israel’s foreign ministry to destroy UNRWA. It believes that UNRWA “works against Israel’s interests” by perpetuating the dream of the right of return of Palestinian refugees and the idea of armed struggle against occupation.
