The creation of an EU army will "weaken" the armies of Nato's member states, Poland's deputy foreign minister said on Thursday. Pawel Jablonski was speaking following statements by a senior EU official, cited by the Reuters agency, on the formation of an EU military force. Reuters reported that 14 EU countries, including Germany and France, had proposed the creation of common armed forces for rapid reaction, which could intervene in an international crisis at an early stage.
