In this week's episode of the "Geopolitical Update" podcast, Joe Varner, Deputy Director of the Conference of Defence Associations, discusses a new annual survey by Stockholm International Peace Research Institute (SIPRI) on global armaments, which found that the number and types of nuclear weapons in development have increased as states deepen their reliance on nuclear deterrence, the impact of a new strategic partnership and mutual defence treaty between North Korea and Russia, incidents involving a Chinese Jin-class submarine near Taiwan and a Russian Yasen-class submarine in Havana Harbor, and Canada's role at the upcoming NATO Summit in Washington. Tune in to the "Geopolitical Update" every Friday for expert commentary on the latest global affairs.
