Wrathgate treason. When Varian stormed Undercity, he saw first-hand the horrors of the Forsaken, including the human experiments down there. He got mad, blamed the whole Horde and decided to end the Horde right there, attacking Thrall and Sylvanas. Jaina teleported the Alliance forces away, preventing a bloody conflict and possibly saving Thrall and/or Sylvanas.
When the orcs were having resources problems, groups of Horde entered Ashenvale and murdered and butchered nigh elf sentinels to steal lumber. This lumber was brought to Orgrimmar. Despite being against the peace treaty between Alliance and Horde, the lumber stealing proved very popular among the Horde, as they saw the much needed lumber as their right. Jaina called Thrall and asked him to denounce and punish publicly the ones responsible. Thrall denied her request because he feared it would lower Horde morale.
When Baine Bloodhoof was exiled from Mulgore due to Grimtotem treachery, he looked for Jaina. Anduin and Jaina offer the tauren the option of joining the Alliance, which Baine refuses, but still Jaina gave him resources to buy weapons and zepelims in order to retake Thunderbluff. Baine got help from Jaina while the Horde itself (except for individual warriors from other races who chose to fight for Baine) did nothing to help him.
With the now Warchief Garrosh becoming more and more violent and dedicated to war, Jaina called Thrall and asked him to intervene. Thrall once again refused.
Theramore is attacked. Baine was part of the attacking forces. A sunreaver Blood Elf betrays Dalaran decision of supporting Theramore's defense and open the gates so the Horde can enter. Theramore is destroyed.
Jaina gets really mad and tries to destroy Orgrimmar in response. Thrall appears to try to stop her. She blames him for doing nothing despite her asking him to multiple times. Kalecgos ends up calming down Jaina, but her trust in Thrall is shattered forever.
Jaina becomes the Kirin Tor leader. She decides to not blame the Sunreavers and still strives for peace.
The Sunreavers betray her trust by stealing the Divine Bell and taking it throught Dalaran to Silvermoon. Jaina orders the Sunreavers to leave, which Aethas refuses. Jaina decides them to purge them off Dalaran, imprisoning them (except those who resist). Despite everything that's happening, the blood elves still choose to give the Divine Bell to Garrosh.
Really, what do you expect from her? The Horde has been backstabbing her all the way. She gave her father over to the Horde and stopped Varian's assault on Undercity hoping for peace, but Thrall wouldn't even punish those responsible on raids against Alliance lands. Both the tauren and the blood elves had the option of leaving the Horde, but still backed up Garrosh.

And to those that defend the rest of the Horde for being intimidated, the only Horde leader with balls to confront Garrosh was Vol'jin. Sylvanas would pose all mighty and high but still do what he ordered of her (because the conquest of Lordaeron was in her interests too). Baine was just silently hoping things would get better. Lor'themar was planning to leave but still chose to steal the Divine Bell from the Alliance (the Divine Bell was brought to him in Silvermoon. I don't buy he didn't know what was happening, or else he's just a incompetent leader). Vol'jin was the first to oppose him, which made Garrosh to try and assassinate him, and he was the one who started the rebellion. And I need to remind everyone that the trolls are one of the smallest populations in the Horde. All the others were just cowards too afraid to face Garrosh or too happy to do his bidding until Garrosh turned on them.
