I understand the posturing. Attacking the EU needs to be presented as a terrible idea, but when people start talking about using nukes loosely, then the other side might also consider them fair game. I guess, in my opinion, using first strike nukes is never justified, and if the EU or anyone does it then they're no better than the aggressors. I would prefer we hold ourselves to higher standards instead of letting the bad actors bring us down to their level.
