Don't miss Bogie Yaalon's astonishing paper at the JCPA site. The most damning charge is this:

It is possible that the prospect of a major natural gas transaction with the Palestinians has been a factor in the Israeli cabinet's refusal to launch a Defensive Shield II operation in Gaza. This concern is a result of the high price Israel has already paid for its relatively muted responses to Palestinian rocket attacks from Gaza. The September 11, 2007, rocket attack by the Iranian-commanded and financed Palestinian Islamic Jihad, that wounded 61 IDF soldiers asleep in their Negev base, is a recent example. Despite hundreds of rockets and mortars, and various terrorist infiltration attempts against Israel from Gaza, there still has been no comprehensive military response by Israel.
