Franco-German relations and a certain froideur.

In France there is increasing criticism of Angela Merkel.  France is strugglin economically
with a blotaed public sector, short working week, Union strangleholds.  Germany want them to cut.
But when you have a populace (voters) who have lived for too long off the state, then life can get very difficult indeed if you wish to change such entreneched views.
So France's endeavours to realign the French economy is faltering and there must be someone ot blame and so the Socialist clique that surround the bumbling Monsieur Holland have decided to blame Angela Merkel.
