Ha'aretz headline: "Barghouti: Shalit abduction achieved what no dialogue could". A ruinous assault on Gaza, leaving the territory in shambles? Well, yes, but something else! The potential release of Marwan Barghouti, currently serving five life sentences for quintuple homicide! And what a shining example of the value of terrorist strikes it is. At the very least, I can understand why Barghouti is excited, as he suffered none of the losses of Cast Lead and already has demonstrated a finely honed contempt for human life. Which makes it unsurprising that he is expected to run for President of Palestine in front of a more hawkish Fatah party, so we can expect more deployment of this outstanding "violence to release killers" approach in the future.
For the record, I suspect that dialogue would, indeed, not have "achieved" Operation Cast Lead. In all likelihood, though, a negotiated final settlement would involve the release of murderers like Barghouti.
