most of them are on other missions as explained

it would be interesting to find that maybe kakashi or some higher class jounins were sent to investigate the akatsuki, either way i'm sure after all this crap with the sound nin's is over it will get back to akatsuki, i think kakashi's mission might have something to do with this.

as for all the other ones, they are probly dumb missions like they were saying just to show the other countries that konoha hasn't been weakened too much and is still keeping up with their daily routine.
