The European Defence Initiative is a proposal for enhanced European Union defence cooperation presented by France, Germany, Belgium and Luxembourg in Brussels on 29 April 2003. It was based on the reinforced cooperation principle and aimed for better reactivity under the European Security and Defence Policy (ESDP).
Some critics felt that this intra-European process would be a source of tension in the transatlantic arena with NATO and some felt that this was a duplication of existing means with the call for a distinct European headquarters. There were also some concerns about a multi-speed Europe. Britain was initially opposed to the concept but subsequently modified its position in favour.[1]
It is sometimes referred to as the "Initiative of the Four".
