Answer:

The costs of non-sovereignty are high.

European countries are increasingly vulnerable to external pressure that prevents them from exercising their sovereignty. This vulnerability threatens the European Union’s security, economic health, and diplomatic freedom of action, allowing other powers to impose their preferences on it.

To prosper and maintain their independence in a world of geopolitical competition, Europeans must address the interlinked security and economic challenges other powerful states present – without withdrawing their support for a rules-based order and the transatlantic alliance. This means creating a new idea of “strategic sovereignty”, as well as establishing institutions and empowering individuals that see strategic sovereignty as part of their identity and in their own interest. Most fundamentally, the EU needs to learn to think like a geopolitical power.
