Mr. Fletcher began his remarks by asking the international community to reflect on what it will tell future generations about action taken “to stop the 21st century atrocity to which we bear daily witness in Gaza.”

He wondered, for example, if “we will use those empty words: ‘We did all we could,’” and urged the Council to act decisively to prevent genocide from happening.

Shrinking spaces, overwhelmed hospitals

In addition to the aid blockade, civilians in Gaza have again been forcibly displaced and confined into ever-shrinking spaces, he said, as 70 per cent of the territory is either within Israeli-militarized zones or under displacement orders.

Furthermore, the few remaining hospitals are overwhelmed, and medics cannot stem the trauma and the spread of disease.

“I can tell you from having visited what’s left of Gaza’s medical system that death on this scale has a sound and a smell that does not leave you,” he said.

“As one hospital worker described it, ‘children scream as we peel burnt fabric from their skin.’”

We can save lives

Mr. Fletcher stressed that the UN and partners are desperate to resume humanitarian aid across Gaza, and the recent ceasefire showed that they can deliver. Meanwhile, lifesaving supplies are waiting to enter the enclave.

“We can save hundreds of thousands of survivors. We have rigorous mechanisms to ensure our aid gets to civilians, and not to Hamas,” he insisted.

“But Israel denies us access, placing the objective of depopulating Gaza before the lives of civilians,” he said.

“It is bad enough that the blockade continues. How do you react when Israeli Ministers boast about it? Or when attacks on humanitarian workers and violations of the UN’s privileges and immunities continue, along with restrictions on international and non-governmental organizations.”

Reject ‘cynical’ US-Israeli aid alternative

Mr. Fletcher recalled that Israel has clear obligations under international humanitarian law, and as the occupying power must agree to aid and facilitate it.

“For anyone still pretending to be in any doubt, the Israeli-designed distribution modality is not the answer,” he stated, noting that among other things, the plan “makes starvation a bargaining chip.”

“It is cynical sideshow. A deliberate distraction. A fig leaf for further violence and displacement,” he told ambassadors. “If any of that still matters, have no part in it.”

He also addressed the increasing violence in the West Bank, where the situation is the worst in decades, with entire communities destroyed and refugee camps depopulated.

Insist on accountability

Mr. Fletcher noted that international humanitarian workers have been the only international civilian presence in Gaza over the past 19 months, and they have briefed the Council on what they witness daily.

“We have described the deliberate obstruction of aid operations and the systematic dismantling of Palestinian life, and that which sustains it, in Gaza,” he said.

The International Court of Justice (ICJ) is now considering whether a genocide is taking place there and “will weigh the testimony we have shared. But it will be too late,” he warned.

He said the ICJ has recognized the urgency and indicated clear provisional measures that should have been acted on – but Israel has failed to do so.

Moreover, previous reviews of the UN’s conduct in cases of large-scale violations of international human rights and humanitarian law have pointed to the collective failure to speak to the scale of violations while they were being committed.

“For those killed and those whose voices are silenced: what more evidence do you need now?” he asked. “Will you act – decisively - to prevent genocide and to ensure respect for international humanitarian law? Or will you say instead, 'we did all we could?’”.

He told the Council that the degradation of international law is corrosive and infectious, and it is undermining decades of progress on civilian protection.

“Humanity, the law, and reason must prevail,” he said. “This Council must prevail. Demand this ends. Stop arming it. Insist on accountability.”

Fear future judgement

Mr. Fletcher called for Israel to stop killing and injuring civilians, and to lift the brutal blockade so that humanitarians can save lives.

He urged Hamas and other Palestinian armed groups to release all hostages immediately and unconditionally, and to stop putting civilians at risk during military operations.

“And for those who will not survive what we fear is coming - in plain sight - it will be no consolation to know that future generations will hold us in this chamber to account. But they will,” he said.

“And, if we have not seriously done “all we could’, we should fear that judgement.”
