As expressed here, all governments are 100% totally responsible if they are not Israeli for everything that happens everywhere in their borders. The US is somehow responsible for all the ills in the world, but most especially the Middle east since right wing Republicans are not calling the shots on US foreign policy. Revenge is deterrence and a perfect motive for Israelis, but not for anybody else. Revenge sears the conscience of all non-Israelis. But for non-Israelis, revenge is terrorism. Randomly shooting non-Israelis is deterrence but shooting back is terrorism. Every idea in this post has already been made in differing language on this thread.
