Lets Get Real:
The EU will play games at the start, but 27 Countries is a lot ot heard, also the Eastern Countries know that it will be British troops who are helping them out against the threat of Putin's Russia, not the Germans or the French. The UK FCO can start to act, have back channel talks with the Eastern block, remind them the security that the UK gives with the Americans. If after a few weeks the EU is still playing games the UK should just walk out, not play games with them, declare WE are out, bin EU laws, make the Germans regret ever winning the peace. The German tax payer will have to cover the UK costs, lets see how they like paying 60 billion Euros to help the Southern States. Talks and Diplomacy is good, but the UK has the stick and we should use it, nothing gets movement better than FEAR.
