One of the lessons of the Iraq war was that our efforts to contain the development of WMDs using tactics short of invasion were more successful than widely believed.

Interrupting the Iranian nuclear and missile program does not require an invasion or any sort of full scale war. The Navy and the Airforce would see combat, as would some specialised units.

A couple days and the Iranian nuclear and missile project is out of business, then a decade or so of an air policing, as was done in Iraq.
