Day and night, our defenders hold the line, protecting Ukraine and keeping our cities and people safe. But by standing up to Russia's full-scale aggression, the Ukrainians are also defending the whole democratic world and the values we all share. To every soldier on the front line — thank you. For your strength, your resilience and your unwavering defence of our country and our freedom 🇺🇦 Photo: Serhii Korovayny for The Wall Street Journal
