At least there are other countries out there that have the will and the means. The US doesn't have to be the biggest and best any longer, and won't be for much longer anyway... China, India, and who knows who else will be out there long before we go back... Pretty soon, all the big announcements, advancements, etc. will be coming from them. Who knows, maybe one day we will be humbly asking China if they'll take us along, or let us spend time on their moon base.
