Poll Majority blames gov’t for Hamas massacre says Netanyahu must resign

Both. People would do well to read Hareetz, Israel's newspaper of record, which is also available in English.

It's hard to accuse it of being anti-semitic. Reading Israeli perspectives, also demolishes the argument that all Israelis don't care about Palestinian suffering or unconditionally support what comes next.

These are some of the opinion pieces they have on their site now:

These were human beings whom Israel dispossessed and expelled, whom it conquered again in their land of refuge and then turned into animals in a cage. They’ve experienced indiscriminate bombardments before, but now the worst of all is ahead of them. Israel has already announced that all the restraints it supposedly used in previous attacks will be lifted this time. Yes, hundreds of Gazans committed atrocious crimes, an outgrowth of 17 years of blockade and 75 years of suffering, with a bloody past and no present or future. But not all of a Gaza is to blame.

This:

Consequently, this needs to be said: Israel has held millions of people under a brutal blockade for more than 15 years with the support of the entire Western world. That is inhumane and inconceivable, and every solution to this bloody conflict ultimately includes respecting the rights of all people, both in Gaza and Sderot, to live with security and human dignity. And that begins with respecting the most basic rules as set down in the international laws of war, which are designed to reduce the harm to civilians.

Or this:

Ironically, those who cheer Hamas's deeds, believing they're advancing the Palestinian agenda, are inadvertently supporting Prime Minister Benjamin Netanyahu's long-term strategy: the existence of Hamas ensures there will be no Palestinian state. More so, it eliminates any chance of dialogue, especially with Palestinians and Israelis already committed to end the occupation.

It can't just be an intelligence failure to have lower security on the Gaza border on the 50th anniversary - down to the same holy day - of the last time Palestinian forces attacked Israel.
