Are we already at war with Iran?

I suspect that we may be, in some way. Maybe a "shadow war."
Someone clearly is killing Iranian nuclear scientists. Someone is messing with
their centrifuges. They seem to be under cyberattack. Someone is helping ethnic
Baluchi rebels down in the southeast. And of course there are the less hidden
steps, such as sanctions.

No, it isn't traditional war, and it doesn't look like
anything John Wayne would want to star in. But put it all together and I do
wonder if we already are in some kind of war with Iran. 

If I were still a hard-working daily journalist laboring in
the vineyard where the grapes of wrath are grown, I'd work on this issue
full-time, covering it on the assumption that there is a war going on in the
shadows. I'd try to cover it as it were a conflict, looking at the steps taken
and the countermeasures, at the major players, at the assumptions about the
other side. It would be tough to do but very interesting. And after a year or
so I'd have the makings of a good book.
