The senior naval officer in charge of America’s nuclear triad says the current worldwide tensions sparked by Russia’s war against Ukraine could be the opening act for a larger conflict that the US must prepare for. In remarks at the Naval Submarine League's 2022 Annual Symposium & Industry Update, US Strategic Command commander Admiral Charles Richard said the Ukraine crisis “is just the warmup”. "The big one is coming, and it isn't going to be very long before we're going to get tested in ways that we haven't been tested a long time,” he said.
