The European Union as it currently stands is the biggest safeguard we have against a recurrence of such horrors. Telle qu’elle existe à présent, l’Union européenne est le meilleur garde-fou contre la répétition de telles horreurs. Surely Europe should act as a safeguard, maintaining a certain equilibrium between increased profitability and social welfare?
