John Simpson, the BBC world affairs editor, shares reflections on his extensive career covering conflicts as he highlights the troubling events unfolding in 2025. He notes the unprecedented level of concern not just for the raging wars but for their geopolitical implications. Notably, President Zelensky of Ukraine has warned that the conflict could escalate into a world war, a sentiment echoed by Simpson given his decades-long experience in reporting such issues. This year has seen significant civilian casualties and international responses, particularly in Ukraine and the Middle East. As the balance of power shifts globally, Simpson urges vigilance in navigating the complexities that could arise as nations reassess their alliances and confrontations.
