I really can't see how you said that all of the akatsuki are much stronger then sasuke, or him not being at jounin level. If he isn't at jounin level then what do you need for it. He's shown strategy in his fights so far, uses techniques in combination with one another and took out an akatsuki member by himself. 2 if you really want to count in a sick Itachi. There's really no way of telling how strong the rest of akatsuki is now,and i have to say they've been taken care of pretty easily up until now with the loss of only 2 ninja on the allied side.

But saying sasuke is weaker then a trained jounin is going a bit far, a young Kakashi was already good enough to be a jounin at a very young age, granted that there was a war going on. I'm not saying he was a good jounin but obviously still good enough to be one.
