In June 2024, the arrival of a Russian naval group, including the nuclear-powered submarine Kazan, in Havana, Cuba, has stirred significant geopolitical tensions. This unprecedented deployment, reminiscent of Cold War-era maneuvers, showcases Russia's capability and intent to project military power near U.S. borders. The U.S. response, involving the deployment of several warships and the fast-attack submarine USS Helena to Guantanamo Bay, underscores the strategic importance of maintaining a robust presence in the Caribbean. This incident highlights the ongoing power dynamics and the fragile balance of global peace between the U.S. and Russia.
