A bombing campaign? You HAVE seen the protests, right? The number of people wanting change is enormous. 30k+ being executed should tell you how brave these people are, and they are still protesting.
The 'troops' are already there; the Iranians themselves. This is Not. Like. Iraq! No IED's, no suicide bombers, no British troops stationed overseas, no security forces, no shitty movies/shows made afterwards.
They've taken out the ones giving the orders. The masses who want change outnumber the sycophants. Does this mean there won't be any violence? No, of course not. Bigots will fight to preserve their oppressive regime. But they are heavily outnumbered with no-one to guide them, to finance them, and the Iranian people are pissed. All they need us to do, is step in again should the control shift back towards the oppressors. A couple more accurate missile strikes has easily sorted that out.
