I'm quite disillusioned about the future of the Union because of ridiculous stunts like this.
Using English exposes people to a certain way of thinking that is more linked to a set of cultures or traditions. It's an undeniable fact, both semantics and linguistics teach us that.
But if the aim is to help politicians think from a different perspective, French is a bad choice. If that was the purpose, a reasonable choice would be to opt for languages related to cultures of more practical rationality.. German or Scandinavian languages
Of course it's the French politicians who have the nerve to try impose their language. Perhaps it has something to do with the fact that French culture is one of the most pedantic and nationalistic in Europe, to the detriment of the other members.
