Nato’s warning reached me as I braced for a missile attack in Kyiv – where we’ve learned how to survive in the era of Russian hybrid warfare

Day 1,024 of the invasion. Kyiv, 7am. Friday the 13th. In a former life, someone would have observed that this is a day that portends bad luck. But in a country where shelling is a daily occurrence, it has become irrelevant. I wake up to the sound of an app on my phone warning me of an increased missile threat. While my partner and I are hiding in the corridor, I read the news that the Nato chief, Mark Rutte, has called on members of the US-led transatlantic alliance to “shift to a wartime mindset”.

With the first bang of the air defence system, a thought strikes me: for those who have not already been living with it for nearly three years, how would you explain this mindset? What is this wartime thinking?
