European Union's Mutual Defense Obligation

European Union nations are bound by a little-known obligation to protect one another. This commitment entails that member states should provide assistance if one is attacked. However, the practical scope and intensity of this obligation still lack specific agreements.

Experts' View on NATO Replacement

Experts have warned that the European Union's mutual defense obligation is no replacement for NATO (North Atlantic Treaty Organization). NATO possesses a well-established integrated military command structure and collective defense mechanisms, which cannot be simply substituted by inter-member cooperation obligations.
