Introduction

The global situation is complex and unpredictable, which is affecting the threat level for each country. In 2025, the Danish Resilience Agency (SAMSIK)[ In Danish: “Styrelsen for Samfundssikkerhed.”] stated that Denmark is navigating its most serious security and risk environment since the Second World War....

Introduction

At NATO's summit, leaders are debating how to counter geopolitical rivals. Yet the most consequential strategic concession may already be underway. The rollback of USAID is reducing Western influence across Africa, Asia and fragile states just as China and Russia expand their diplomatic, economic and security footprints.

The transatlantic order that underpinned European security for decades can no longer be taken for granted. As Washington retreats from development and diplomacy, Europe faces a strategic choice of whether to fill the vacuum or accept a diminished role in shaping stability beyond its borders.... Read more

Introduction

The U.S. military operation in Venezuela reported on January 3, 2026 serves as a contemporary illustrative case of a timeless problem: contradictory judgments issued within 72 hours. For some, it was a “brilliant tactical success”; for others, a “predictable strategic failure.”¹ This phenomenon is not new. Limited military operations display a recurring pattern: categorical strategic judgments issued within days are later refuted or substantially qualified.² This study examines why such assessments exhibit an elevated risk of analytical distortion and how Intelligence can mitigate the problem...

California, a U.S. State, continues to suffer from deeply rooted systemic issues with violent crime, many of which stem from its fragmented immigration enforcement and political obstruction of coordinated law enforcement. While the state bears direct responsibility for its choices, the federal government has also failed to assert consistency and operational control. Both levels of government have allowed the situation to spiral by misaligning priorities, underutilizing intelligence, and letting political identity override security imperatives.... Read more

It is necessary to admit that every subject that is derived from the so-called “hybrid war”, it is very difficult to be defined. In both Theory and Methodology of International Relations we need to define concepts and essences because it is essential to conduct a framework. Without a definition (with relative clarity) it is almost impossible to observe, analyze and solve a problem. The great difficulty comes when the restricted clarity of a definition affects negatively the framework or the scheme that we want to conduct. Hybrid War is an excellent paradigm of this kind of difficulty.... Read more
