To be honest, I didn't see any feats shpwing Tsunade or Sakura strong enough to break that meteorite. I'm not saying she can't. Just don't she can.

Kakashi should have mastered a barrier jutsu, and teach three ither capable shinobi to master it too, something like the Hokage's barrier jutsu. That would have easily protected the village.
