If it is due to the Husky, then it's fear. You summed it up almost perfectly:
I believe she is afraid that another dog is going to do what the husky did so she is reacting before they have a chance to.
That's fear aggression in a nutshell =)

So if it is fear, the two basic suggestions are DS and CC: desensitize and counter condition. At this point, I don't think DS is really all that relevant or necessary, but definitely counter condition strange dogs and think about giving her an alternative job to do.

Does she pay attention to you in public spaces? What about in dog parks? If no to both, then work on basic obed. with distractions. Gradually work your way up to basic obed. in the dog park, away from other dogs. Then, you can do it in the pit of it all. You want to build up her confidence and let her know that other dogs aren't a big deal and that they won't hurt her. If she starts to zone out, take yourself out of the situation and try to do the basic obed. in a quieter place. Alternatively, you could just ask for eye contact/focus. If she's showing a lot of stress signals (sniffing, zoning out, frantically roaming all over the place), take her out of the situation and try to see what her trigger is and at what point the triggers start to get at her.

Aggression is a p.i.t.a to deal with, but it's really rewarding once you work past the nitty gritty Ivy and I can COMPLETELY relate!
