So let's see. Jaina's father was anti-Horde and most of her friends were too. She resisted and tried to give reasons on why the Alliance and Horde should get together and fought for that.
Then for so much she gave to the Horde, when she asked Thrall to just investigate the incident in Ashenvale and let the Alliance see the results, he refused. He placed Garrosh as a leader, and Jaina warned Thrall that it won't be good. He ignored her. She sheltered Baine and some tauren and helped them take back their city still but she also let Alliance troops pass through Theramore territory (yes, pass, since the Alliance troops did not attack Stonemaul, the Horde outpost in Dustwallow, and I doubt it is because they could not). So she played for both sides. And then Garrosh prepared for an attack. She gathered everyone to defend, not attack, again, as, even with the Horde ships that tested her resolve by sailing just outside Theramore waters, she didn't signal the attack on them.
And for that, the Horde threw the mana bomb. They wanted war? Fine, but they used a weapon of mass destruction. They killed everyone in Theramore except her. Her friends, subjects, people who trusted them, all were killed. Some like her apprentice were turned to dust. That is what the Horde gave her, for killing her father to protect peace, for helping Baine retake Thunder Bluff most of those she knew were killed. And the civilians were captured by Garrosh and taken for target practice in Orgrimmar.
And then Thrall dared come back to lecture her? After she warned him not to put Garrosh in power? After he did nothing when Garrosh used molten giants and dark shamans? And the mana bomb? But of course he'd want to protect Orgrimmar... as an orc.
But still Jaina calmed down.
She became the leader of Dalaran. Varian came to her and asked her to join the Alliance. She refused. She didn't trust Garrosh though so she found artifacts and hit them where they were safest. The Divine Bell, in Darnassus. There's no way Garrosh would get to it and she could trust the night elves not to use it ( let's be honest now, night elves are like squirrels with dangerous artifacts and people, they take them and hide them, that's what they did with the Well of Eternity by putting a tree over it, that's what they did with demon hunters, hiding them in caves not marked on maps etc, this is why giving them the Divine Bell was the best). But then someone used her city, her neutral city, Dalaran, to steal the Divine Bell from Darnassus. The Horde. And while not all the Sunreavers were guilty, this action forced Jaina's hand. To prove to the Alliance that Dalaran was not leaning Horde, she'd now have to actually do something for the Alliance. She gave the Sunreavers a choice, leave or be imprisoned. Many refused and raised arms even if the Horde tried to break Dalaran's neutrality and this proved it. It proved that they were actually trying to start a civil war to force Dalaran to become Horde!
So it was not just orcs she can't trust, it is the whole Horde!
During War Crimes she did come to the conclusion that not all Hordies were pro-Garrosh, but still, by not doing anything against him, they were accomplices. Like the Sunreavers that knew, they were supposed to be loyal to Dalaran, but showed that they were only loyal to Silvermoon. Even if she, Jaina, kept Dalaran safe even after Garrosh killed Rhonin and destroyed Theramore, a town where some in Dalaran had friends/loved ones. She was loyal to Dalaran, but the Sunreavers were untrustworthy, because they are HORDE! She may not truly hate them, but she'll never trust them again, they know nothing of loyalty, of friendship, of a greater goal, they can only understand fear and betrayal. They could still be worked with against greater threats like the Legion, but only under close watch.
This is how I understood Jaina's reasoning, and it makes perfect sense to me.
