They stay prepared but do absolutely nothing even after Jaina kills some of them.
The purge was justified, but how she went about it was abyssal, for example using the silver covenant was a big mistake
She used Kirin tor resources to help the alliance against horde infiltrators. She was not neutral herself.
The entire thing was orchestrated by garrosh to blame the sunreavers

Garrosh sabotaged his diplomatic efforts by organizing a heist in Darnassus and focusing blame on the blood elves
The council never ceased to exist and her voice was not more important that those of the others, they might have agreed after everything was said ad done but not immediately.
She killed all of the guards, despite them doing nothing.
She is not the boss of Dalaran, never was, she can't do anything without the other council members.
Yes Aethas was guilty of inaction, that doesn#t mean all Sunreavers are guilty
It was never her city, Antonidas never appointed. Jaina was appointed the head member of the six in tides of war, ironically her biggest supporter was Aethas.
She killed them, there was no reason to do that, at the time she didn't even know for certain who was responsible, she just acted on her emotions.
Again Jaina has not more say in decisions that is not how Dalaran works, the council needs to reach consensus.
Horde and Alliance were at all out war at the time, Jaina helped the Alliance keeping the bell from the horde, thus breaking neutrality herself.
The night elves merley took the bell and the shen'dralar were keeping watch over the bell, some of the most scumbag highborne to ever exist.
Highborne are night elves, they are the same race.
