Long-term thinking: Find and divert an ice asteroid/moon into Mars atmosphere at the proper angle. Even tho most of it would “burn up” it would still add some necessary components to the Martian atmosphere. And some amount of water/ice as well.
I read there’s ice aplenty circling Saturn. There’s probably some in the asteroid belt, who knows that?
A few thousand of them possibly
Without a strong magnetic field (as Earth has), solar wind would just blow the additional atmospherics right off (over time)...
Our moon - and how our Earth-moon system came to be - is apparently quite unusual, and is responsible not only for our planet being so stable, but also for having such a rich atmosphere.

That would be man made climate change therefore not possible for US to do it. The Russians or some other country could and it would be OK.
