Tensions surrounding the Ukraine conflict have heightened as Russia issued warnings regarding potential nuclear conflict, coinciding with the EU's firm stance on sanctions and the disputed annexation of Crimea. The EU has maintained its position, refusing to lift sanctions against Russia or formally acknowledge the annexation.
Sergei Shoigu, Secretary of the Security Council, asserted Russia's right to use nuclear weapons in response to aggression from Western countries, even in the event of a conventional attack, citing the updated nuclear doctrine. Concerns were raised about European military preparations, with Shoigu suggesting that troop deployments in Ukraine could escalate into a direct confrontation between Russia and NATO, potentially triggering a larger conflict.
These warnings emerged after unsuccessful peace talks in London, where disagreements persisted over the recognition of Crimea as Russian territory and the partial lifting of sanctions. Meanwhile, efforts towards European involvement in Ukraine talks faced setbacks following the cancellation of a meeting in London. Trump's special envoy, Steve Witkoff, has been actively involved, planning his fourth visit to the Kremlin this year, with Trump claiming to have a potential agreement with Putin to resolve the conflict, contingent upon Zelensky's approval. However, reports indicate clashes over easing Russia sanctions, with Secretary of State Marco Rubio opposing the idea.
Adding complexity, Russia's updated nuclear doctrine, adopted in November 2024, outlines conditions for nuclear weapon use, including responses to attacks on its territory or that of its ally, Belarus, even with conventional weapons that pose a critical threat. This has sparked debate and concern over the blurring lines between conventional and nuclear conflict.
