Someone has to stop Israel's rampant madness in Gaza

Gideon Levy has courage. Being in the middle of all the jubilation, proud smirks and chest thumping madness, this Israeli writer with conscience writes in Israel's prominent newspaper Haaretz what needs to be written about Gaza and deaths of more than 1100 of women, men and children and that the number is continually growing with increasing pace.
"In the streets, people are running back and forth in panic, holding children and suitcases in their hands, helpless as the shells fall around them. Nobody in the diplomatic corridors is in any hurry to help those unfortunates who have nowhere to run.

The handful of journalists trying to cover the events, despite the outrageous media closure Israel has imposed, are also in danger. The Israel Defense Forces Thursday shelled the media building they were in and now they are all crowded in one office, as fearful and horrified as the rest of the scorched city's residents.

This is how Israel now looks to the outside world - its tanks in the burning streets of Gaza; more and more people being killed for nothing; tens of thousands of new refugees; an appallingly haughty foreign minister, and a growing clamor of condemnation and disgust from all over the globe."
Can only the verbal condemnations and disgusts stop this murderous onslaught? In the face of mighty tanks and supersonic killers in the sky, can all the good wills, candle light prayers, silent tears in one's solitary moment seeing the blood drenched images from war's gruesome reality be any "game" changing factor?

These all goody woody feelings and in many cases sincere gestures toward the oppressed ones surely can surmount to boisterous protests around the world as has already been rumbled on icy to heated streets. But what would definitely affect the outcome is the protesting in meaningful way like the time when South African Apartheid was dealt its final knell. Naomi Klein writes in The Nation: "
Economic sanctions are the most effective tools in the nonviolent arsenal. Surrendering them verges on active complicity. "
