Not new, just newly declassified. It's important to note though, because it gives lie to the emerging "Hamas is responding to what the IDF did in May" theme that anti-Israel activists, diplomats, and reporters have recently taken to trial ballooning:

We're in no position to give the IDF advice about anything, except maybe things like "if you're being given strategic suggestions by an ex-union thug who unfortunately landed the Defense portfolio because idiot Israeli students decided to lodge anti-establishment protest votes, consider a second opinion". But it seems to us that these strikes would be significantly more successful if they were carried out when the Qassam rocket makers were in the Qassam rocket making factories.
