Ker se ZEU in NATO še dogovarjata o modalitetah sodelovanja ZEU/NATO v operacijah, ki jih vodi ZEU in v katerih uporablja sredstva in zmogljivosti NATA, so strokovnjaki EU in ZEU ob upoštevanju v Amsterdamu dogovorjenih sprememb v odnosu EU/ZEU skupaj izdelali priloženi shematski prikaz medsebojnih povezav kot ponazoritev postopkov sprejemanja odločitev v EU in ZEU in njihove vmesne faze v kriznih razmerah, v katerih se za oblikovanje in izvajanje odločitev in ukrepov EU, ki so obrambnega pomena, zlasti Petersberških nalog, EU obrne na ZEU.
Whereas the modalities for WEU/NATO cooperation in WEU-led operations having recourse to NATO assets and capabilities are currently under discussion in the WEU and NATO, experts of the EU and WEU, taking into account the modifications in the EU/WEU relationship agreed in Amsterdam, jointly elaborated the attached flowchart as an illustrative example of the flow of the decision-making processes in the EU and WEU and their interfaces in crisis situations in which the EU avails itself of the WEU in order to elaborate and implement decisions and actions of the EU having defence implications, notably on Petersberg tasks.
