As the Middle East is facing grave uncertainty against the backdrop of what is being called the 'Third Gulf War', Ankara is managing an uneasy relationship with Iran.

Turkey is projecting itself as a more consequential regional actor across a variety of regional security spaces and is often described as a 'middle power'. In this episode of Global Security Briefing, Dr Neil Melvin is joined by Dr Burcu Ozcelik, RUSI Senior Research Fellow, to analyse Turkey's relationship with Iran and the main limits of Turkey's regional approach to diplomacy.

This episode explores:

· How Turkey approaches peacebuilding in the Middle East.

· What Turkey's regional role is across different theatres in the Caucasus, Somalia and Iran.

· The limits of eastern Mediterranean security architecture that excludes Turkey.

· What British and European policymakers should learn from Turkey's approach to diplomacy.

This podcast episode is part of a policy series for the 'Turkey's Peacebuilding in a Disordered Middle East' project of the Centre for Applied Turkey Studies (CATS) network.

The US and Israel have launched major strikes on Iran, triggering retaliation across the region and raising fears of wider war.

As tensions escalate around the Strait of Hormuz and across the region, the implications extend far beyond the Middle East. In this episode of Global Security Briefing, Neil Melvin is joined by Dr Burcu Ozcelik, RUSI Senior Research Fellow, and Dr Roxane Farmanfarmaian, a specialist on Iranian and regional politics and an Associate Fellow with RUSI, to analyse the regional and global significance of the crisis.

This episode explores:

• What the US and Israel are seeking to achieve, and how Iran is responding.
• Whether the strikes could threaten the survival of Iran's political system established in 1979.
• The risks of escalation and miscalculation across Iraq, Lebanon, the Gulf, and the Red Sea.
• The prospects for leadership disruption, succession dynamics, and elite cohesion inside Iran.
• The potential roles of Russia and China as diplomatic or strategic actors.
• The UK's response and whether it has adopted the right approach.
• Key scenarios for how the conflict may evolve in the coming days.

Ukraine, its European backers and the United States have drawn closer to agreeing a blueprint for peace, but various questions remain.

Can anyone accept Russian sincerity? How to treat Moscow's demands for territory in the Donbas, and beyond? And what is to be made of Russia's attitude towards security guarantees for Ukraine?

In this bonus episode of GSB, we hear from a panel of experts on the prospects for peace, four years on from Russia's invasion of Ukraine. Their remarks were recorded during a RUSI event on Tuesday 24 February 2026: Recording: Ukraine: Prospects for Peace, Four Years After Russia's Invasion | Royal United Services Institute.

In an hour-long discussion, the RUSI panellists, including Dr Neil Melvin, Director of International Security, Matthew Savill, Director of Military Sciences, Dr Maryna Vorotnyuk, Associate Fellow and Dr Jonathan Eyal, Associate Director, tackled a wide range of questions relating to:
