As US-led talks with Russia and Ukraine progress without the Europeans at the table, the 27-nation bloc is pressing ahead with what Ursula von der Leyen has branded a steel "porcupine strategy". In her words: "We need to make Ukraine strong enough to be indigestible for potential invaders". Her plan aims to build the Ukrainian armed forces and the country’s defence industry into a formidable opponent for Russia to give Ukraine a hope of self-defence in the future. But can Europe find the money to help Ukraine?
