Israeli ceasefire possible explanation

there is some Western military opinion that Israel agreed to this cease-fire - which on the surface seems like a really stupid move on its part - because the Israeli military leadership concluded that its young soldiers were not up to snuff and needed more training, and perhaps by the time Round 2 rolls around, new Israeli political leadership would be in place with the stones to tackle the job full bore. "Delay and better prepare" is a theory, at least, that would explain the seemingly unexplainable.
