Sergei Skripal, a former colonel in the Russian military intelligence, turned double agent for the British intelligence service MI6, was found critically ill along with his daughter, Yulia, in the small city of Salisbury, England. Authorities determined they had been poisoned using a sophisticated nerve agent known as Novichok, a substance developed in the Soviet Union. The bizarre circumstances surrounding their collapse led to a rapid investigation by British law enforcement. The UK government quickly blamed Russia for the attack, asserting that the novel nerve agent pointed to the Kremlin's direct involvement in the assassination attempt.In the wake of the poisoning, the UK's Prime Minister, Theresa May, announced that the British government would respond strongly. This led to the expulsion of over twenty Russian diplomats from the UK and spurred allies across Europe and North America to do the same, resulting in a wave of diplomatic expulsions totaling more than 100 Russian diplomats worldwide. The incident substantially escalated tensions between the West and Russia, evoking memories of the Cold War. The Skripal case not only raised the stakes in international relations but also spotlighted issues of espionage and chemical warfare in contemporary geopolitical discussions. The international community's response highlighted the fragility of diplomatic relations in an era of renewed hostilities and the ongoing concerns regarding state-sponsored terrorism.
