Excellent post by Kosmopolit:
1. Not sure how the EU works or what institutions are involved? -> Just write "Brussels".
2. Germany is generally seen as important in EU politics and journalists know how to frame it:
If Germany is active in a certain policy domain just write something about "German dominance" and if you work for British newspaper add some subtle references to the war.
If Germany is passive in a given policy area just write that Germany abandons the EU and it clearly adopted a unilateral strategy, if you work for a British newspaper you could add something about the war.
3. Found a short reference in a paper which talks about your country? -> Is is an evil plan to undermine democracy
4. General rule: No need to distinguish between different European institutions and organisations. Who cares whether it is the Council of Europe, the European Council, the Council of the EU, the European Commission, the Court of Justice of the European Union or the European Court of Human Rights . -> Just write something about eurocrats and unelected foreign European judges interfering with your beloved country.
I am lazy on this Sunday morning, so I won't add anything, but recommend you read the entire piece.
Endnote: This does not help: EU bans claim that water can prevent dehydration.
