Get ready to watch the European version of the American Civil War.
The powerful people in Brussels in 2011 won’t be willing to let member states secede from the EU without a fight any more than the powerful people in Washington, DC were prepared to let member states peaceably secede from the US 140 years earlier in the spring of 1861.
There is too much power and wealth at stake for this to have a happy ending.
I don’t think that the EU possesses its own military.
I have said for along time that the EU would be the cause for the next European Civil War, (there is always another one).
Granted the EU does not have a military as such, but they could certainly cause a nation that does to do their fighting for them.
Additionally, if the EU breaks up, watch for the rise of a “strongman” type leader.
