The independent resource on global security



On 3 January, the leaders of the five permanent members of the UN Security Council (China, France, Russia, the UK and the USA, the P5) jointly stated that a nuclear war cannot be won and must never be fought. It had never been affirmed simultaneously by all five.

On 15 November, Russia conducted a direct-ascent anti-satellite (DA-ASAT) test, destroying one of its own space objects, a defunct satellite, in low-earth orbit. The test captured international attention and was quickly and widely condemned as threatening and irresponsible—not least for the cloud of lethal, uncontrollable debris it created, which will endanger both space assets and human spaceflight for years to come.

Libya’s electoral limbo: The crisis of legitimacy

Eleven years after the downfall of Muammar Gaddafi, the situation in Libya remains extremely volatile. Elections planned for 24 December last year did not take place and the electoral process collapsed. As a result, Libya entered yet another period of deep political crisis, at the heart of which is (once again) a struggle over how to create a legitimate, national government.

War in the breadbasket: Hunger and the humanitarian fallout from the war in Ukraine

Russia’s invasion of Ukraine will have a serious impact on both local and global food security. The humanitarian crisis in Ukraine is only the beginning. Since the conflict threatens global food supply, there will be far-reaching repercussions for humanitarian actors. Already prior to the war, humanitarian needs outpaced the response to meet them. This reality deserves attention. Also, it is critical to understand the risks to food security in order to have a better chance of managing them.  


Organized environmental crime has become one of the fastest-growing types of organized crime. In many conflict-affected contexts, it is the primary source of financing for non-state armed groups. In the light of this, how can peace operations and other multilateral actors respond to conflicts which are driven or sustained by activities that involve illegal exploitation and trade in natural resources?

Approximately 452 million children were living in a conflict zone in 2020, and almost half of the roughly 80 million forcibly displaced people worldwide are children. Many of the countries most affected by conflict are developing countries with a young and growing population.

The Missile Technology Control Regime is a cornerstone of states’ efforts to control the development, proliferation and use of missiles and other unmanned delivery systems. However, it faces serious structural, operational, membership and technology-related challenges that call for new initiatives and a strengthening of the regime’s resilience.
