This is why I asked for clarification if this was an EU sanction as I see no reference of it, only that line that "France" sanctioned 25 people / companies. If this was an EU sanction France done the name of it in, then it would mean indeed the EU does not comment of every sanction enforcement as I can see no reference of it and that would weaken my own argument that the EU staying quiet on us enforcing the sanction. So I would be weakening my own position but happy to do so.
Well I don't think there is much point in carrying on with this issue, you're apparently reading into the lack of response from the EU to suggest something along the lines of them not agreeing with the sanctions they came up with? That is highly dubious as already pointed out considering they specifically target Iranian entities within the regulations. The simpler explanation is them not wanting to stoke a delicate situation with Iran while they're trying to hold together then nuclear agreement.
I'm going to take an Occam's razor approach here and suggest that the Iranian nuclear deal is the relevant factor.
Like I said before we can agree to disagree, if you want to stick with your narrative for the silence from the EU then that's cool. Questions about whether or not some enforcement action appears on some web page you're interested in etc.. doesn't seem particularly relevant here.
