Actually the real question is "what would Zionists do without Hamas?"
Netanyahu has helped Hamas get funding, members of his cabinet have called them an "asset", they have consulted them for government decisions, and he has spoken openly about supporting them as a way to prevent the establishment of a Palestinian state.
He needs a boogeyman, and Zionists and Hamas think exactly alike because both reject a two-state solution. They even say the same thing. Sound familiar?

He only reacted this time because they did something no one could ignore (as he has done in the past), and it was a handy distraction from the protests against his autocratic behaviour. Does anyone really believe his claim that he is going to destroy them? He needs them.
