This report maps out the evolution of key technologies that have emerged or developed in the last 4 years of the war in Ukraine. Its goal is to derive the lessons the North Atlantic Treaty Organization (NATO) could learn to strengthen its defensive capabilities and prepare for modern war, which is large-scale and conventional in nature.

European countries can no longer avoid the "Russian question," as Russia has chosen war. They have the necessary potential—that is, the economic means, military capabilities, and technological expertise—to face Russia by 2030, provided they demonstrate the political will to do so.

As Russia continues to threaten Europe, the Trump administration is making no secret of its desire to withdraw—at least partially—from the defense of the Old
Continent in order to focus on strategic competition with China. It is thus putting pressure on its European allies to increase their investment in the military sector. The NATO Summit in The Hague in June 2025 resulted in ambitious commitments by member states to increase their defense spending.

During his state visit to the United Kingdom (UK) last week, Emmanuel Macron, President of France, signed a joint declaration with Sir Keir Starmer, Prime Minister, on nuclear cooperation between Britain and France. The Northwood Declaration highlights that while both countries’ nuclear arsenals remain sovereign, cooperation on nuclear deterrence can ‘contribute significantly’ to the security of the North Atlantic Treaty Organisation (NATO) and the Euro-Atlantic region.

As international relations have become increasingly unpredictable, the quest is to find a semblance of normality. Alliances are shifting as interests are changing. The so-called order established after the Second World War is being shattered by those who have given so much to create it. Global relations are being transformed by countries that wish to follow the rules and others that want to circumvent or ignore them. In this uncertain environment, it is therefore all the more crucial to find stable allies.

Confronted with a U.S. disengagement and the Russian threat, Europeans are reconsidering their stance on nuclear deterrence. Given the capabilities of the French and British arsenals, can Europe develop an independent nuclear deterrent?

The evolving landscape of global defense cooperation has brought the transatlantic relationship between the United States (US) and Europe into sharp focus. As geopolitical tensions rise and the threat environment becomes more complex, the question of how Europe can best ensure its security while navigating its relationship with the United States has become paramount. This double feature report offers two contrasting views on the dynamics of US-Europe defense industrial relations, highlighting the challenges and opportunities that lie ahead for both parties.

The Europeans' worst security nightmare seems to be coming true: on Tuesday, February 18, 2025, U.S. Secretary of State Marco Rubio and Russian Foreign Minister Sergey Lavrov met in Saudi Arabia to initiate the normalization of relations between their two countries. The meeting also aimed to set up peace negotiations for Ukraine. However, despite having the potential to affect the entire continent, the discussions took place without the Europeans or the Ukrainians being present.
