As was reported recently, the only electrical power line that can be shut down (due to the presence of hospitals etc.) is the one servicing Beit Hanoun. This will be a minor unpleasantness for the Palestinians and it does stand to reason that the Qassam barrage will get stronger. And Gaza has little economic activity going on now, so who needs cars and fuel. The militants will get their fuel first, in any case. As the writers predict, the measures may make the Qassam problem worse. So what is the purpose of the exercise? I find it hard to believe that the IDF wants to get in and fight Hamas in Gaza. Perhaps the security people are at their wits end and are trying to do "something", as earlier they came up with the brilliant idea of firing cannons at EMPTY places. The best way would have been to allow Abbas to engage with Hamas, which is willing to let him negotiate and bring the result to a referendum. People who reject such an approach are capable of every stupidity. It shows.
