I definitely like the idea of downsizing some of our military footprint, but I wonder if it might be a good idea to add some guidelines for what "useful" means. We have bases in a lot of areas, from western Europe to Eastern Europe, the Middle East, and the Asia-Pacific region. I'm not an expert on military bases, but I'd guess there are a lot of different reasons why some of those are there and could be useful for different reasons. It might be a good idea to add in a veto power too in case there's something very important that gets overlooked by the committee.
Indeed, we may want to outline what criteria these decisions would be made upon to help guide the committee through the process.
