Well, I think Leia got kicked out of the New Republic when people figured out that Vader was her father. And I'm pretty sure the resistance was to fight against the First Order, not the New Republic.
100% agreed. The New Republic was such a disaster that it wasn't even believable in the sequel trilogy, which was one of many (many, many, many) things they were criticized for.
I do like how they are expanding on that in The Mandalorian by showing that it was infiltrated and sabotaged by imperial loyalists. In fact Tim Meadows' character in this meme was one such imperial loyalist infiltrator. So it's not that they were solely incompetent due to having no plan. But their plan was to rehabilitate and assimilate the former imperials, but the rehabilitation part failed, so former imperials pretended to be rehabilitated and then just sabotaged the New Republic.
They are expanding on it out of necessity, and I believe it is just retconning because of how poorly thought out the sequel trilogy was. But I am enjoying the story we are getting out of it nonetheless.
I thought immediately after this conversation with Carson Teva (Paul Sun-Hyung Lee), Colonel Tuttle (Tim Meadows) immediately gives that information to Elia Kane (Katy O'Brian), who then gives it to Moff Gidean (Giancarlo Esposito).
Perhaps I misinterpreted him speaking with Elia Kane as working with her. But for sure Elia Kane was an imperial infiltrator. Perhaps they weren't working together.
I vaguely remember that. I think when I watched it I interpreted it as him naively sharing information with her. Perhaps it was part of her duties to collect the data, she did seem fairly high up the New Republic's information stream.
I think you're right. I just read through the script of that scene, and I think Colonel Tuttle was just doing his job. Elia Kane inserted herself into the conversation and confirmed that Tuttle shouldn't help Nevarro at this time, then got more information out of the conversation while Carson Teva was only trying to help.
So yeah, on second thought, I don't think Tuttle was imperial, only Kane.
