What do you actually know about it, and what do you think of it?
I'll go first, writing from a British perspective.
I'll be honest, I'm a Eurosceptic - I regard the EU as authoritarian, undemocratic and usually corrupt to greater or lesser degree. Moving the EU Parliament from Brussels to Strasbourg for 12 parliamentary sessions just to satisfy French vanity is a colossal waste of money and to me sums up the EU's unaccountability to the citizens of the member countries.

Moving the European Parliament:

Although I think there's been an outbreak of common sense:

Fingers crossed - I don't like my money being wasted by Government quangos.

I also believe that the EU can never function as a single entity - each country ultimately follows it's own agenda and picks it's allies depending on what's being discussed. For example, one week Britain and Poland could work together against a German initiative, the next Poland could work against the UK in pursuit of it's own interests. Normally Germany and France work together and generally don't get on with the UK, although France and Britain work together on defence matters - mostly. This to me is not a good combination. Despite the efforts towards greater European integration, national interest normally trumps it.
The EU is the political model of the Solarian League! It just doesn't have an analogue for the SLN.
Yet.
France is the main mover behind greater military integration in the EU, whilst Britain is opposed to the concept as it believes it will weaken NATO. There's also some suspicion in British conservative circles that the French are doing it just to put one in the USA's eye. They also think that most of the smaller nations will effectively freeload, meaning that it'll mainly be British and French troops filling the body bags.

In addition, I think that trying to get the Germans to contribute anything militarily is like pulling teeth. The Bundeswehr may have good equipment, but training standards are supposedly not good:

Problem is, it's the German's who have the money and their loath to spend it on anything militaristic. I guess getting pummeled in two world wars does that....
So, I don't think Europe will ever manage to be a cohesive military power. Too much grit in the gears!
Britain has a long tradition of Euroscepticism and the Conservative party has promised to hold a referendum on the UK's membership of the EU if they win the next election here.
Here's a selection of articles on British Euroscepticism and the Wiki article on the proposed referendum:

Would the UK actually vote to leave the EU if the populace was given the chance? There's a good question. Like the outcome of the Scottish Independence Referendum this September, it's impossible to predict with any real certainty.
