Given US President Donald Trump’s uncertain commitment to Europe’s defence, calls for greater European strategic autonomy have grown louder. However, Benjamin Shreer argues that while the approach of Trump’s government is certainly complicating transatlantic security relations, the current arrangement for Europe’s defence anchored on NATO for collective defence and complemented by EU military capabilities for limited out-of-area operations is unlikely to change. A US withdrawal from NATO is equally doubtful, as is the prospect that European countries will become serious about developing strategic autonomy.
