Also, this won't be another Iraq. Iraq and Afganistan were wars without goals, and the goal became to stabilize their countries. It was also started by the west. If Iran starts a war against Israel, then Israels job is to, make them give up or at least destroy their military. These kinds of war have a target and doesn't last very long. I mean, US could have moved out when they decleared victory, or when they got Saddam. Then US would have been out of Iraq a long time ago. They didn't because they are trying to stabilize Iraq.
