Cost of non-Europe - Potential efficiency gains through greater cooperation in Common Security and Defence Policy

The efficiency gain from closer cooperation at European level in the area of security and defence policy is thought to range from some 130 billion euro at the high end to at least 26 billion euro per year, on the more cautious estimate used here. If Member States were to operate in a more integrated manner, they would need to spend significantly less than their current collective defence budget of 190 billion euro.
