True, there are talks about the EU army and further expansion. In my opinion, this is only matter of time. Some countries will try to postpone it, like Poland, Greece, Croatia, but eventually it will happen (for better or worse).
I'm also not a fan of how politics is done sometimes in Brussels (like how Greece is undemocratically forced to sell property and change it's economy to become more pro free market), but I believe that democratic change is best achieved by working within the system. For me, there are still enough benefits in being member of the EU (substantial investments in local industries, cooperation between universities, good deals in free trade of services and products, etc.).
I hope we can stay friends after the Brits have their Brexit. I am also wondering how long Gr. Britain will exist if Scotland is slowly making it's way towards independence in hopes of being part of the EU. This will certainly change the dynamic in our relationship (fishery, subsea oil fields, etc.)
