If the Unites States stops playing policeman of the world and stays into it's own domain, like China does, then they can use a HUGE amount of the military budget to go elsewhere. Going back to the moon? What to do on that pile of sand and dust without atmosphere? The only convenance is that it's close by. Mars is the same shithole. Also a desert with nothing fancy there and also no atmosphere to protect us against deadly solar rays and also dearly cosmic rays. There is just ONE place which could be ideal for humans to colonize, and that is TITAN.
Granted, it's a little further away and the moon is also a bit more colder, but who cares? Other than that, Titan has at least a descent atmosphere, putting surface pressure at a relative comfortable 1.45 bar. So no pressure suit needed. The atmosphere provides protection against either Solar or Cosmic rays. The moon even lies within the safety of Saturn magnetic field. Extra protection. It has weather, it has seas of liquid methane and ethane and a lot of other hydrocarbons. Low gravity and thick atmosphere makes flying so easy that humans can fly themselves with wings attached to their arms, making logistics on this moon very easy and cheap. And as said, no need for pressure domes. Only bringing oxygen to breath and a lot on insulation against the cold.
