Several times in the past Israel decided it was so powerful it could take on the world (70 and 135 come to mind). To be completely honest, I don't have any stake in there being an Israel, but I would hate a war in which millions of people die. Israel seems to have decided they can ignore the EU, US, UN and everyone who calls them on their increasingly irrational actions. I'm afraid of what will happen.
