This will cause the residents of Gaza to suspect Hamas even more, and spread paranoia between Hamas members.

Viva Israel!

I can only surmise that Ms. Hass` piece was passed the the Israeli censors. Should it have slipped by, she should be tried for treason. If the methods she has described are true, then she has placed some very brave men`s lives at risk for the sake of her political views. Will she offer her condolences to the mother of this or that undercover agent, explaining that it was more important to demonstrate how unfair the war against Hamas is and that she is unfortunately responsible for the death of this mother`s son, done purposely to ease the suffering of the Palestinians, a plurality or perhaps a majority of whom would slit her throat as well if given a chance of getting away with it. Her views would in no way have saved her skin if Hamas had been the successful combatant in this conflict.

The testimonies of Gaza Strip residents are revealing new details about the Israel Defense Forces' mode of operation there. In the past two days, Beit Lahia residents forced from their homes said soldiers were posing as members of Hamas' armed wing while advancing on the ground. Link

What’s more, the story has been scrubbed from the Haaretz news site. Here is a google snapshot and here is a mirror of the article at war in Iraq. There is only one problem with this tactic - what if Palestinians learn to say "shibboleth?"
