If anyone else in the EU could have made up for what the US providing, why didn't they do it from the beginning? The answer is, "they can't." No one else in the world has the US's logistics, intelligence, and heavy lift capacity. The US provided it in Libya, it is providing it in Mali, and most likely will have to do it if any EU country wants to do anything meaningful in Syria.
Spain's contribution in Mali is significant only for the fact that they sent anyone at all. But comparing a country giving up a company-sized element of ground troops, a couple of LAVs, and a whopping TWO cargo planes to what the US providing is foolish.
