You have for sure not understood what the Holocaust has taught to the Jewish People. Israel will ask NO ONE if she comes to the conclusion that the horror that Nazi Germany brought upon the Jewish people could be repeated. Remember the USS Liberty that came to close to the codes for the Israeli nuclear deterrence? Remember the last warning to Iran just a few weeks ago against the will of the US when Israel bombed Syria? When it comes to self-defence, Israel has to ask no one. And Israel must not wait until the point of no return has been reached. What has been achieved in decades with sweat and blood of the Jewish people will not be destroyed by a few fanatical medieval mullahs in Tehran.
