EU leaders will meet in Brussels to discuss a common defence strategy and financing, addressing significant gaps in military capabilities. The informal retreat aims to foster open discussions without expecting joint conclusions. Key topics include prioritizing military investments and securing funding, especially in light of potential threats from Russia. There is a growing consensus on the need for a more autonomous European defence, influenced by shifts in US foreign policy. The meeting will not result in immediate decisions but is seen as a crucial step towards finalizing a White Paper on Defence.
