As for a first strike, highly unlikely, they know the cost of such a gamble and a particular heavily nuclear armed frenemy to the north of them would be none too pleased.

Europe knows that opening up trade relations, dropping adversarial positions, etc. would probably yield better results. In our case, Iran would want a full apology which is something we almost never do.
