They don't want to be reliant on NATO due to the influence USA, and whoever their president may be, has over it and want something in house instead.
I personally think that having a European Army is a bad idea just because of the humongous funding required to keep something like that ticking. At the moment USA foots the bill quite nicely paying almost 3x the amount that the other members so they should stick to being freeloaders from a cost perspective.
