I don't think that there is some kind of conspiracy theory here, but there is no reason you'd need an invasion to stop the attack. Simply refraining from moving soldiers outside the Gaza border and into the West Bank would have been sufficient. It was 3000 thousand terrorists with light weapons, it wouldn't have been difficult to stop if Netanyahu hadn't sent so much of the IDF to terrorize civilians in the West Bank and steal their land.
