Russia's been a brutal kleptocracy longer than I've been alive. It's slapped a fresh veneer on a couple of times, but that's about it. Despite this, after the burst of progress after WWII and the decline afterwards, here we are decades upon decades later and Russia is still able to launch rockets into space. We laugh at them because they're generally not consider as safe as other nations' space programs, but they do it. For a while longer, anyway.
Maintaining capability is a lot different from creating new capabilities. The US is diving so rapidly and enthusiastically into the kleptocratic model, combined with a revival of rabid anti-intellectualism, that I don't think it will be able to establish a lunar base before it finds it has lost the ability to engineer one.
