First off, this point needs to be reiterated. There is a lot of assumptions in to the supernova, and we don't have all the facts. So, assuming that the Federation is simply like *shrug* at the supernova is hasty, at best.
Thus far, as people have pointed out, that's not what happened. A fleet was assembled, and it was attacked and destroyed. They said "No" to putting in more resources after losing so many. It has nothing to do with hate and everything to do with resource management.

There were members of the Federation who were never on-board with the rescue. The attack on Mars allowed them to get the upper hand stopping any attempt, even a half-hearted one, from continuing. In that context, it looks like the Vulcans tried one last desperate gambit to stop the coming calamity.
But that was when Ross and the Romulans were on a break.
Yep, after end of DS9, outside of Worf, how many times has DS9 been mentioned, or even hinted at that it was still around? I can count on one hand and have most of my fingers not used. DS9 does not/will not get any love from producers, ever.
The Berman era is over, though
I don't see it as cynical. I see it as an effort to present challenges to future humanity. Challenges that, largely, humanity has faced again and again throughout its history. Optimism comes from the belief that one can rise above those challenges and be successful in defeating them, not that challenges will never occur.
DS9 is simply more "inside baseball" than TNG.
Different strokes, different folks. Each series has its strengths and weaknesses.
Indeed, yes. Failure is also apart of the human experience. How it is handled is always the question. If they handled it poorly then that gives us, the audience, an opportunity to discuss it.
