Pansies can't win because pansies won't fight. That is quite completely all.
121 Killed & 628 wounded are the numbers that I’ve seen, excluding Israeli civilian casualties. That pretty much makes a brigade-size force combat ineffective.
I should add that there was a lot of criticism within the IDF on their seeming inability to keep their forward combat troops adequately supplied. Now that happens in almost every mobile war, but in such a shallow incursion or when the fighting becomes more or less static, that is an indicator of a planning problem.
