Israel-Iran War: Does Israel Have The Right To Go To War?

Does Israel have the right to go to war? What does God say about war? All the leaders of Iran say it very clearly, "Our goal is to wipe Israel off the map. So, what would God want Israel to do? Would God want Israel to sit back and listen to a threat and not take it seriously? Well, let's roll back in history about 88 plus years ago, when there is a man in Vienna and then in Germany by the name of Hitler came up with a plan to kill every single Jew. Hitler did on his threat and he started the war where 60 million people died. Here we have another enemy who said the exact same words, repeating the words of Haman, repeating the words of Hitler, that their life goal, their life mission is to annihilate Israel. So, what says God? There's evil and there's good, but God gave us rules of engagement. And he made it very clear, "Anyone who is coming upon you to kill you, you must kill them first because God wants you to value life, not death."
