In Europe, Ukraine is often seen as a petitioner and a recipient of aid. In reality, it has been safeguarding Europe’s security and freedom for more than three years. Today, Ukraine not only fields the largest and most battle-hardened army in Europe, it also covers 40% of its defence needs through domestic production and boasts a vibrant Mil-Tech ecosystem. Looking ahead, Ukraine therefore must be a cornerstone of the European security and defence architecture that must increasingly stand on its own.
