Russia’s foreign intelligence chief, Sergei Naryshkin, warned of retaliation against NATO countries aiding Ukraine in long-range missile strikes on Russian territory. He emphasized that changes to Russia’s nuclear doctrine make it difficult to defeat Russia militarily. Naryshkin cautioned NATO allies against facilitating such strikes, as they would face consequences. This follows Ukraine’s use of U.S. ATACMS missiles, approved by the Biden administration. Naryshkin highlighted the West’s growing awareness of Russia’s serious intentions and the potential catastrophic consequences of direct conflict.
