[World of Warcraft] Why don't the Gnomes call to Jaina or someone for help to reclaim Gnomeregan?

The gnomes have been living in Ironforge for such a long time because they can't reclaim Gnomeregan. Why don't they ask someone like Jaina who is immensely powerful?

She could clear it out it in like, 10 minutes and they would have a home again.

There was a large effort to retake the city around the time that Deathwing started torching the countryside.  Portions of the city were reclaimed at that time, and there are continuing efforts to recapture the rest.  Since the gnomes are making progress, heavies like Jaina probably think that their efforts are better spent elsewhere.  It's likely also true that to cleanse the city you need lots of technical labor (patching up holes, cleansing radiation), work for which the gnomes are well-suited (even if they're taking their time about it).
