Defense and Security

The sudden announcement of a US-Houthi ceasefire, brokered by Oman, has halted Washington’s air campaign in Yemen and raised urgent questions about the future of Red Sea security. What prompted the deal, and what are its implications for maritime shipping, regional alliances, and the trajectory of Yemen’s civil war? This episode explores the strategic motivations behind the ceasefire, the role of Iran and Saudi Arabia, and how the Houthis could leverage the pause to regroup and expand their influence across the Horn of Africa.

On March 10, 2025, Ahmed al-Sharaa, the president of Syria, and Mazloum Abdi, the commander-in-chief of the Syrian Democratic Forces, signed a historic agreement, ending a long-running divide between Damascus and the Democratic Autonomous Administration of North and East Syria. Now, two months after the deal was signed, how far has it progressed, and what are the main obstacles and disputes between the parties during this transitional phase?

Iran is accumulating enough near-weapons-grade enriched uranium to build a nuclear weapon within weeks or months, not years. President Donald Trump, having withdrawn the United States in 2018 from the nuclear deal that would have postponed that possibility, is now appealing for negotiations with Tehran. But in the Middle East, the nuclear question does not concern only Iran.

After decades of managing tensions through careful balancing, Turkey and Iran now find themselves increasingly at odds following recent shifts in the regional balance of power. With Ankara emboldened and Tehran on its back foot after the fall of the regime of Bashar al-Assad, the struggle for influence between the two neighbors and long-time rivals is escalating in both Syria and Iraq and could spread well beyond their borders.

The work of the Syria Strategy Project and the considerable policy recommendations found in this report present a realistic and holistic vision for Syria’s recovery and reintegration into the international system.

President Donald Trump’s joint address to Congress on March 4 doubled down on his disruptive and contentious domestic policy agenda. Foreign policy, including Trump’s approach to the Middle East, was mostly an afterthought. Though he said little about Middle East policy in his speech, Trump’s team is taking an irregular approach on the twin issues of Israel-Arab ties and Iran that may not produce the stability and prosperity it seeks.

Afghanistan’s neighborhood is in the midst of a consequential restructuring of its security architecture. Key regional actors Pakistan, Afghanistan, Iran, and China have been continuing to adjust their defense plans and security partnerships to meet the growing threats posed by domestic and cross-border terrorism. At the same time, these four countries have also been looking for new ways to fill the vacuum in southern Asia left by the United States military’s departure from Afghanistan.

Either maintaining Russia’s military bases in Syria or finding an alternative outpost in the Mediterranean will prove extremely difficult for Moscow. And part of the problem with pursuing the latter option, particularly if in Libya, is that it would require a full-on transformation of Russia’s military presence model — from more traditional bases designed to establish deterrence by showing the flag in the region to building up a military and logistical operation inside a security “gray zone.”

A very different Middle East will greet President-elect Trump this month compared to the region he experienced during his first term. However, there are opportunities to advance American interests for a more stable and less conflictual Middle East, which might not require the kind of intense US commitment we have seen over the last quarter-century.

Russia’s full-scale war against Ukraine has provided several strategic opportunities for Iran to increase its foothold in the Greater Black Sea Region. A closer analysis of Iran’s deepening footprint there is necessary to inform how the next administration in Washington and the new European Commission can strengthen and better coordinate their policy responses.

To abandon the Syria mission now would bring no meaningful benefit to the US, but it would swiftly and significantly empower America’s adversaries, like ISIS, Iran, Russia, and Assad’s regime.

The multiple wars that have erupted since Oct. 7, 2023, have already changed the strategic landscape in the Middle East — and more change is likely to follow.

The Black Sea has recently become one of the world’s most important dynamically shifting geostrategic maritime areas, with Ukraine playing a crucial role in upending the naval balance of power there. Ukraine’s efforts to push back against Russia, bolstered by Western military aid, have challenged the status quo and reshaped the region’s security landscape.

This policy assessment examines the statements and positions staked out by the Harris and Trump campaigns on the Middle East. The spotlight is on the past few weeks, with a stronger focus on two main issues that are likely to dominate the regional agenda of the next US administration: Iran and Israeli-Palestinian affairs.

It is no exaggeration to say that the Islamist political system in Tehran is on the brink of experiencing perilous blowback for the foreign policy choices it has made. Whether Tehran continues to prioritize the fight against Israel or decides to look for ways to deprioritize the conflict as a national security matter will not be settled in the foreseeable future — or perhaps the matter will be taken out of Iran’s hands.
