Hardly conclusive.
The invasion was preplanned and was an act of reprisal against the Palestinian people for having the audacity to protest decades of oppression and abuse.
That's nonsense and you know it.
Not nonsense, but a major misinterpretation of the facts.
Of course the invasion was to some extent preplanned. If it wasn't the Israeli generals should be court martialed for dereliction of duty. Israel perfectly well knows there are going to be more incidents with Gaza and any competent military makes plans to deal with expected threats.
That's not to say that there was an intention to actually execute the plan until Hamas started throwing a whole bunch of rockets.
