So how will the EU handle a military junta attacking a democratically elected member state?

What is the penalty to the junta members? Complete annihilation and seizure of all assets? Or will the penalty be soninadequate to make military coup an attractive option?

Does the EU have the ability and intestinal fortitude to deal with a member state coup?
Is there anything written in the EU documents to cover such a situation?

Australia's federal model used the American Civil war as a test case so that the Australian Consitution spells out that once a nation joins to become a State it cannot leave by law. Also State power is moderated to avoid such an issue.

So my question is did the EU frame the exit policy at the start with foresight or is it a matter of make it up as they go along and ignore all lessons learnt by other nations who have fused (UK,USA etc)?
