Following recent developments in the Middle East, the Policy Center for the New South is launching a three-part webinar series on the strategic, geopolitical, security, and economic consequences of the US-Iran conflict. 

Building on the publication Hormuz and the Invisible Fractures: The Price of a Distant War – Views from the New South, the series examines the Strait of Hormuz as both a vital maritime chokepoint and a fault line in a changing global order. While the recent U.S.–Iran agreement has eased immediate tensions, the crisis remains ongoing and continues to evolve, making this publication a timely snapshot of a dynamic and still-unfolding geopolitical landscape.

Drawing on the volume's multidisciplinary analysis, the webinars explore the conflict's implications for the New South, global trade routes, energy security, and the evolving international order, while fostering informed discussion on the long-term strategic lessons emerging from the crisis.

This session explores how the US-Iran conflict is reshaping relations among major global powers. The discussion assess the impact of the crisis on transatlantic cohesion, the evolving positions of Europe and the United States, and China's strategic calculations in this changing environment. Particular attention is being paid to the implications for global governance, great-power competition, and the emerging international order.

    The New York Times reported this morning that after the shot down of an U.S. drone by Iranian forces, President Trump ordered military retaliation, but called it off in the early phase. Below is a facts' review through the international press perspectives. “You are pushing everyone towards a confrontation” Unusually, the satellite images were not presented to the media. Possibly, the photos were taken from a submarine, or there was fear that the enemy could figure o ...

    Les Etats-Unis ont alternativement défendu le système westphalien et fustigé ses principes d’équilibre des forces et de non-ingérence dans les affaires intérieures d’autrui en les prétendant immoraux et démodés. Il leur est même arrivé de faire les deux à la fois. Ce qui ne les empêche pas de continuer à affirmer la validité universelle de leurs valeurs pour l’édification d’un ordre mondial pacifique et de se réserver le droit de les soutenir à l’échelle planétaire.

    The trade tensions between the United States and China will cause only minor immediate damage to their giant economies. However, tariffs have important and diverse effects on individual sectors and cause heightened uncertainty. The main adverse effects on Sub-Saharan Africa will therefore be through global investor confidence, economic growth and commodity prices, and these effects could be severe if the dispute escalates further and endangers the rules-based trading system. The tra ...

    TEARS OF JOY CHANGED INTO THOSE OF PAIN January 28, 1986. It was just another day in the whirlpool of news and speculations of a new Foreign Correspondent to be assigned to the White House. Shivering on his way to the most important political center of the Western World, resisting arctic cold and snow on the way to work, hardly ever seeing the President himself. Instead, he found himself on this fateful day in a rendez-vous with Tom Foley, majority leader in the House of ...

    “ARE THEY PLAYING US? I DO NOT KNOW” There they were, the North Koreans, covered by red flags, and more red flags — a Hollywood production indeed. Were the soldiers singing? There was nothing to sing about since they're marching for endless hours, being scrutinized by cameras and bothered by aching pains of hunger, unable to speak and stimulate their voice. The colonel in charge of the marchers may discover some rusty spot on a belt buckle or a truck on parade may run out of fuel - ...

    “NONE OF AFRICA’S PROBLEMS CAN BE RESOLVED THROUGH MILITARY FORCE” Colonel Raul Rivas arrived in dress uniform, his parachute citations well polished. His ribbons for bravery and combat duty were aligned at the upper left-hand side of his jacket, a colorful display of combat, death and battles in Afghanistan and Iraq.  The Colonel, just a few years above 40, and despite his 21 years in the military, was as “proud of being an American as one can be,” a true patriot. He jumpe ...
