Ahead of the special European Council meeting that you scheduled for 6 March, we write to urge you to resist a dangerous and false dichotomy: the idea that increasing defence spending must come at the expense of international development assistance (ODA). Cutting aid would be both a moral failure and a strategic mistake. At a time of growing instability, hunger, and global crises, when conflict, climate disasters and inequality are worsening, Europe must reaffirm its commitment to multilateralism and solidarity, and show global leadership. We know the only way to meet the daunting challenges of our time is together.
