There is a robust history of using exercises, wargaming, and simulations to inform capability gaps, decision-making, doctrine development, and overall strategies. From the success of the fleet problems of the US Navy in the interwar years to less successful strategic bombing principles developed during the same era, the effectiveness of such wargaming and exercises often comes down to assumptions, realism, openness to new ideas, and buy in from the larger organization on the need to improve and change. In today's landscape, many of these events either are white celled to prevent escalation to nuclear exchange or effectively end once nuclear hostilities commence. While exercises such as GLOBAL THUNDER do have learning elements to them, their effectiveness at modernizing nuclear doctrine in the evolving international arena with multiple actors could be up for debate. What models exist that could enhance nuclear-focused exercises, wargames, and simulations across the nuclear enterprise for tomorrow's challenges while still focusing on keeping operational deterrent forces on-alert to face today's threats? What organizational culture elements would have to also be addressed to enable organizational learning and development vice the safeness of the way we have always done things?
