And God laughs...
Ground wars for control of large swaths of territory are obsolete. By the time the muzzies rallied to start a ground game they would have already been decimated.
To launch an assault by land into Israel you would first have to knock out its satellites as well as any humint and elint currently active. You would also in that time frame, destroy the IAF.
Basically it will be more of the same. Launch thousands of scuds and what not into Israel and hope you hit something of value.If Israel does find out it is a Iranian proxy war, they should go with the 12 hour limit to get stop or Tehran becomes a parking lot. This way they can show the world what Iran is planning.
