Iran made countless explicit threats to exterminate the Israeli state, backed these up with 80,000 rockets sent to Lebanon, used to bombard israeli civilians (having no military application - too inaccurate). Iran previously orchestrated bloody attacks on Israeli embassy and a local Jewish community center in Argentina in 1994. Now unambiguously obvious that Iran is developing nuclear weapons and missile delivery systems and that Israeli cities are the target. What do you think the Jews of the world would have done to Hitler's Germany in 1938 if we held 400 nuclear warheads then, and knew what we know now - especially the inaction and apathy of the rest of the world? Martyr-obscessed Shiites are not deterred by the concept of Mutual Assured Destruction, and Israel is not going to just sit around waiting to be nuked - or sucker enough to trust the rest of the world to prevent it. Is 65 million dead Iranians the only way to stop their genocidal plans? No viable alternative is apparent.
