I wouldn't trust a bare syllable out of that mad-dogs' mouth. He is an arch war-monger.
I don't think Israeli boots on the ground is realistic though. Iran has a near 1 million personnel in the military.
I think the idea is to humiliate Iran through Israels superiority in the air, crippling the functionality of the government and trying to invoke a peoples revolt against the Islamic regime when energy and food shortages arise next winter.
