Over the past year of war in Gaza, several diplomatic and humanitarian organisations, including the UN, have repeatedly accused Israel of breaching rules of military conduct. These breaches have provoked regular condemnation by governments and high-ranking officials worldwide. But amid all the words, what has been missing is concrete action against Israel.

If any authority has the power to influence Israel's actions, it is the US – its strongest ally and main source of military aid.

The death toll in Gaza has passed 42,400, with thousands more bodies thought to be buried under rubble and tens of thousands dying from indirect causes. In Lebanon, where densely populated neighbourhoods are being hit by air strikes, at least 2,300 have been killed and 1.2 million displaced.

Earlier this year, the International Court of Justice determined that it was plausible that Israel may be committing genocide. Investigators and human rights groups, including Amnesty International, have warned the US that it may be complicit in war crimes because of Israel’s unlawful use of American weapons.

In a rare development this week, a leaked document revealed US officials warning the Israeli government that future weapons shipments could be affected if the humanitarian crisis in Gaza is not addressed within 30 days. But with little having changed in the past year, and as Israel appears to defy any limits imposed on it, the question remains: will the US truly enforce any red lines?

On this episode of Beyond the Headlines, host Nada AlTaher speaks to Hala Rharrit, a former US diplomat who resigned in protest against Washington’s handling of the war. She also speaks to Mark Schwartz, a defence researcher at the RAND Corporation, to examine the White House's support for Israel. And we hear from Alex Vatanka, the founding director of the Iran programme at the Middle East Institute, on the prospects of an Israeli retaliation against Tehran.
