This is an old divide and conquer strategy that they have been engaging in for a while now. The Israeli right needs to keep the public afraid of them to stay in power, and promise security that way. It's a stupid strategy if the goal is security, but the goal of theirs is far far more sinister.

I'm pretty sure Netanyahu miscalculated, he probably knew there will be an attack, but underestimated the scale of it. He was probably hoping to use that to strengthen his position and take off heat from his judicial reform programs, but he underestimated the extent of the attack.

Fascists tend to be very arrogant...
