MOSCOW, RUSSIA – A definitive peace agreement between Russia and Ukraine is impossible as long as the Russian dictator, Vladimir Putin, remains in power and alive, according to Sir Laurie Bristo, the former United Kingdom Ambassador to Moscow. Speaking on the Battle Lines programme on 19 December 2025, the veteran diplomat warned that the world is currently navigating its most volatile period in modern history, characterised by systemic risks and a breakdown of traditional international norms.
Sir Laurie, who led the British mission in Moscow during the 2018 Salisbury poisoning, argued that while a ceasefire is desirable for almost every global stakeholder, the core of the conflict is rooted in the dictator’s personal imperial ambitions. He noted that the Russian leader views Ukraine not as a sovereign state, but as an integral part of a Russian empire and a Western project designed to undermine his authority. Consequently, Sir Laurie dismissed the idea of a territorial compromise, stating that the Russian dictator’s worldview cannot be reconciled with Western interests or Ukrainian sovereignty.
Reflecting on the evolution of the conflict, the former ambassador admitted that Western nations were too slow to recognise the reality of the threat posed by the Kremlin. He highlighted the 2008 NATO summit in Bucharest as a pivotal turning point where ambiguous signals regarding the membership of Ukraine and Georgia provided the Russian dictator with both the motivation and the opportunity to intervene militarily.
The diplomatic landscape has also been complicated by the deepening military and political ties between Russia, China, and North Korea. Sir Laurie emphasised that the current era of confrontation requires a modernised diplomatic machine, though he defended the continued necessity of maintaining embassies in hostile capitals. He argued that the primary roles of an ambassador in such environments are to deliver unfiltered messages to decision makers and to provide the nuanced intelligence required to predict an adversary’s next move.
Addressing the 2018 nerve agent attack in Salisbury, Sir Laurie defended the UK’s decision to expel 23 Russian intelligence officers rather than pursuing more escalatory measures at the time. He explained that the coordinated expulsion of over 150 spies across the NATO alliance was intended to impose a tangible cost on Russian intelligence operations and demonstrate Western unity, despite the subsequent “torrent of lies” and disinformation from the Kremlin.
