Dmitri Medvedev, the former president of Russia, has transformed into a prominent social media provocateur for the Kremlin. Recently, he successfully challenged US President Donald Trump, prompting the redeployment of two US nuclear submarines. Once celebrated for his stance on Russian openness towards the West, Medvedev now champions an ultra-nationalist agenda, engaging millions of followers online. This shift highlights the evolving dynamics of international relations and the influence of social media in shaping global politics.
