Who implied that about the Feds and the Romulans?
Sloan and Section 31.
Let's remember the events of Nemesis and the spirit of cooperation there.
Yes, but that was a TNG movie and thus it was more optimistic and not in the vein of DS9.
The Dominion's been doing their thing for thousands of years, one guy saying "Wait a minute" isn't going to change anything. He can work as hard as he wants, but his hard work won't pay off. And the Female Changling (before the Treaty and the cure) pretty much was going on about how in the end the Dominion would triumph anyways. I doubt them being cured would change that attitude since they were all dying from a virus introduced to them even before the war started.
Yes, and their planet is still an utterly trashed place full of death and persecution and angry folks whose real satisfaction came not from peaceful coexistence but from their oppressors suffering nearly and equal genocide and devastation. Violence and strife was simply rewarded with an equal amount for the others instead any sort of peaceful future.
I was referring to Bajor actually, not Cardassia.
Cardassia suffer massive genocide and the all but total annihilation of their industrial base and infrastructure, and even if it is rebuilt odds are the rebuilt planet will just be a pacified puppet state for the other powers and never allowed to be it's own place anymore.
All the "O'Brien must suffer" episodes would leave a bad mark on anyone, and considering that it's no wonder he accepted the offer and left no matter what good memories there were.
He secretly hoped that one day through his efforts he'd be able to go back to Cardassia. He works hard to do so, ultimately becoming a different man than he was, only when he gets there it's a ruin and odds are it'll never be the place he loved so much to begin with anymore.
They ARE wasting their time, they just don't realize it and don't understand the odds or greater circumstances they're going against. That's not hopeful, it's delusional.
Here are the most glaring example of Anwar's extreme
negativity, cynicism and nihilism, which makes him a huge
HYPOCRITE.
1) He subscribes to the views of
LUTHER SLOAN of SECTION 31 of all people (!!!), and insists that Luther Sloan's view and Section 31's predictions for the future must be true!
2) He completely denigrates Odo's noble efforts and hope he has to make his people understand others and change their xenophobic views, showing them the love and friendship he felt in relationships with solids. Even though there is NOTHING in the show itself to suggest that Odo's efforts will be in vain - on the contrary, DS9 finale ends on a note of hope - Anwar is just too eager to shoot it down. And based on what? On the argument "They have been like that for thousands of years, they are never going to change".

No comment necessary.
3) Furthermore, Anwar takes a character who is a known racist and genocidal mass murderer (the Female Changeling), as representative of an entire race, while ignoring and disparaging (as naive and idealistic?) the opinion of a character who believes he can change his people for the better (Odo).
So, for Anwar, the characters in DS9 whose opinions and predictions abotu the future are worthwhile are Luther Sloan and the Female Changeling. Brilliant. Is Anwar seriously suggesting that a show's message is likely to be conveyed through opinions of two supporting villainous characters who are both genocidal criminals, rather than through opinions of the show's main characters, and far more sympathetic characters, such as Odo?
4) He suggests that Bajorans felt
satisfaction from Cardassians suffering genocide and destruction! This is completely Anwar's interpretation, as the show didn't show any Bajorans gloating over the fate of Cardassia or saying "Serves them right" or whatever. Anwar is the one arguing that the majority of people are likely to feel that way. So, either he thinks that Bajorans are in majority vengeful and racist (I would like to see arguments for that one), or that most people in real life generally are vengeful and racist, or that Cardassians "deserve what they get" as some kind of "poetic justice", which in itself would be an incredibly ugly and racist statement.
Less cynical people, like myself, saw what happened to Cardassia not as some kind of "poetic justice" or cosmic punishment, but as an example that the historical roles change all the time and every state, race and group of people can be oppressor or a victim, depending on the circumstances. Just like the Changelings were the oppressed for so long, then turned into the biggest of oppressors, before nearly perishing as victims of genocide.
We didn't really see many Bajorans express what they feel about the Cardassian fate, but the one we did see, Kira, didn't show any satisfaction or pleasure in seeing the devastation and deaths of Cardassians. She did have a moment when she couldn't help reminding Damar of the parallel with what Cardassians had done on Bajor, but it was not presented as a moment of gloating, but rather as a case of asking "Do you understand now?" (and for which she immediately felt bad), and most importantly, this was presented as a moment when a Cardassian military officer like Damar starts to understand for the first time the mistakes of the past and the wrongness of what Cardassians had done on Bajor. The show emphasizes the difference between the people who can't understand the mistakes of the past or decide to let go of old prejudice (Rusot), and those who can (Damar, Garak), which allows them to become heroes and build a new Cardassia.
After the end of war, the show let Martok voice the callous sentiment "Who cares about the dead, they are Cardies" which, realistically, would be some people's reaction, but it is doubtful that it would be the reaction of the majority, and certainly not of everyone who has historically been an enemy terms with Cardassia: and the show has its main character, Federation Captain Sisko, and a Federation Admiral, voice the humane reaction of sorrow over the deaths of millions.
5) As for O'Brien - to argue that he left DS9 because he hated being "tortured" is just ridiculous. None of the torture and unhappiness he suffered had anything to do with people of DS9, they were all caused by outside forces, and he had no reason to feel any resentment towards the station itself, where he also had many more happy moments. There is nothing in the show itself to suggest that O'Brien resented or hated the station or his friends - that is another thing that Anwar is choosing to read into the story.
There is a huge difference between realism and nihilism. But apparently, for some people like Anwar there are just two possibilities: fairytales where everything is 100% happy, sweet and hunky dory and everyone is perfect, and a more realistic world which they tend to see through dark-coloured glasses. The nihilistic and cynical messages are not messages that DS9 is trying to send, these are so obviously messages that
Anwar wants to see and the ones that he wants to impose on everyone else, and to do so, he has to use the most cynical and nihilistic arguments. The level of hypocrisy is really astounding.
