At least there are war/prime directivey reasons for those. They didn't want to help the Romulans literally out of space-racism. lol
That's sort of the problem with having such a long standing mythology where writers keep trying to mine drama by creating conflict within the Federation.I would be way more excited about the "Rebuild the Federation" stuff, including the touching stuff with Sahil at the end, if I had confidence that the series would simultaneously try to examine both why the Federation might be a source of hope and also why it might be something that fell apart because of its flaws, or weaknesses. "The Federation was wonderful, and remaking it will make everything better" is a boring story. "The Federation was flawed, and here are some of the ways it hurt people, but now we have a chance to make something new and better" would be, well, better
Given that they're doubling down on Section 31 by having a whole series about it, I assume no one is actually interested in trying to deal with those types of problems though.
