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.

Since the killing of Hezbollah leader Hassan Nasrallah at the end of September, Israel has expanded its air strike campaign in Lebanon and launched a ground invasion. It has also struck Yemen and Syria in recent weeks.

Meanwhile, Hezbollah has launched a series of rocket attacks towards Israel, which for the most part have been intercepted. At the same time, the war in Gaza is continuing as Israel devastates the north of the enclave.

The other major escalation was Iran directly striking Israel with ballistic missiles for the second time since April. Israel has now vowed to strike back. But when and how?

Until now, Iran has relied on its proxy groups in the Middle East. At first, it was unthinkable that any major world power would want to get involved in a war of that scale. Neither the US nor Iran seemed to want to venture to that point of no return. However, tensions have escalated.

In this episode of Beyond the Headlines, host Nada AlTaher looks at the potential consequences of these recent escalations. We hear from Paul Salem, vice president for International Engagement at the Middle East Institute, and Dr Sanam Vakil, Middle East and North Africa programme director at Chatham House. They analyse how Israel could respond and the geopolitical risks the warring sides may or may not consider.

Over the past year, reporters, photographers and even children have documented the atrocities in Gaza through their phones, using social media to show the world the horrors they endured.

People all around the world erupted in protests against the war, demanding a ceasefire and later an arms embargo to Israel. But negotiations between the warring parties failed and failed again. UN Security Council resolutions also failed, with the US using its veto power to reject almost every one.

Despite strong warnings from the international community, the war has spilt over across the region. So-called “axis of resistance” groups periodically launch attacks on Israel. Israel has assassinated key Hamas and Hezbollah figures, each time heightening tensions both in the region and around the world.

And now, almost exactly one year after October 7, Israel has expanded its war into Lebanon, hitting the heart of Beirut for the first time in recent history. It has also struck Yemen and Syria. Its air bombing campaign in Lebanon killed Hezbollah leader Hassan Nasrallah and soon afterwards it began a ground invasion into the country’s south. Iran has since launched a barrage of missiles and drones towards Israel, as both continue to threaten one another with more retaliation.

As the situation in the Middle East escalates, where are we today and where do we go from here? In the third and final episode of our series covering one year of war since October 7, host Nada AlTaher looks at the fading attempts to end the war. She also picks at old wounds to understand why, decades later, all efforts for a diplomatic solution to establish a Palestinian state have failed. She speaks to Palestinian ambassador to the UK Husam Zomlot, and to political analysts, and asks the difficult question: what future prospects for peace can there be, if it’s not already too late?
