As has been said in this European column and in many other publications in recent months, the current economic crisis – particularly the sovereign debt crisis – has brought the European Union up against its limits. It is, in fact, very difficult to take the decisions that are required at the economic level without efficient authorities of governance. With 27 members and a system of decision-making that requires unanimity for matters of “vital interest” (the definition of which may differ substantially from one country to another and stray far from the general interest of the European Community as a whole), the Union hardly possesses the political means to fulfil its ambitions. This is what Jean-François Drevet shows here, reminding us of the EU’s decision-making system, the way it was constructed and the limitations it has experienced over many years. It is a system urgently in need of reform – without doubt towards a more federal mode of operation.
