Many people in the Israeli government have been quite explicit about Hamas’s actions being useful to them as a pretext for doing so, too.
So, while I am not arguing that is is the case, it is not at all implausible (especially if the underjudged the scale or likely impact of the attack) that they might allow an unusual attack that was likely to be pretextually useful to occur to provide an excuse to bring the hammer down, even before considering the specific, personal pressures on Netanyahu and how he might view an excuse for a justified war as a means to deflect them.
