Sorry, my dear Yossi Sarid, but Israels "credibility" problem in the world was certainly not caused through this (rather minor) incident. That "job" was done by the chronical cheating/ tricksing of pretty much the whole political establishment in Israel when it came to issues like settlement expansion or route of the fence/wall in the past. No need at all to blame "Bibi" alone for that image.....
