How do you think the united states won the cold war/ Iran by pursuing alledged nuclear arms, missile technology whilst arming Syrian and Lebanon amongst othersto put financial strain on Israel as they try to counter Iran's threat. Problem is Israel doesn't have oil money but iran does, and if the price falls to low then a bit of sabre rattling raises the price. Which Israel falls for hook line and sinker every single time. Iran's aim is to push the boundaries as far as it can without overstepping the line and forcing Israel to spend serious amounts of money on weapons systems such as Arrow, which will never be used. Even having a second strike ability costs serious amounts of money compared to having a bunker with a couple of bombs in it in central Israel. It's all about making life in it's current form to expensive for israel.
