Donald Trump's return to the White House is a wake-up call for Europe, as it faces increasing security challenges that require a reassessment of its strategies. Europe can no longer rely solely on the United States for protection and must prioritize its own security while reinforcing its role within the broader alliance framework. The threats posed by Russia's aggression in Ukraine and Iran's growing influence are deeply interconnected and require close collaboration between Europe and the US. Europe must actively support Israel and moderate Arab states in countering Iran's global destabilizing efforts. The recent US election serves as a reminder that failure to address these threats could jeopardize political stability and the safety of European citizens.
