This book shows how France and Britain are leaders in EU security and defense policy, and explains why both states need each other in this policy area. The lack of relevant military capacity in Europe today implies that the US favors a strong EU in this field.
Values and Weapons looks at the determinants of legitimacy for using military force in the US and Europe. Sovereignty has been redefined to be conditional on democratic government, and this makes it much easier to intervene into non-democratic states.
