If Iran believed those documents surely they would have gotten their people out of Lebanon before Israel cut loose - did they??
Well, I don't know at this point. It's a chaotic situation that may have blown up more quickly than expected. (One should always expect things to blow up more quickly than expected!) I suppose the Iranian elements could be literally stabbing terorists in the back, by Southack's analysis, but, I dunno... that seems like a stretch. Also possible is that there are Iranian elements in Lebanon not currently completely under Iranian gov't control.
