Broom,
none of the national governments want an EU DF. this means it cannot happen.
some of the beaurocracy want an EU DF, because, well, who doesn't want their own Army, but such things are not theirs to fund, form, control or own. they are solely the preserve of the national governments, and while you can always find an idiot to speak stupid words, none of the national governments are actually interested in an EU DF.
thats not to say that there can't be, or isn't, co-operation, joint venture etc.. but everything is the preserve of the national governments to decide to engage, or not engage, on whatever basis they like.
