A large and diverse collective defence for would be impossible to command and develop  It does not take an in-depth analysis to imagine the issues, on the ground and at HQ, such as army would face. There would be communication issues, would the force use French, Spanish or English? There would be accountability questions [1] , who would be in charge and who would pay for resources? Finally, there would be hostilities within the army and potentially inherent racism between the nations involved. Such a force would not be effective in a combat situation, and valuable lives and resources would be wasted.  [1] Ioannides, I. (4 September, 2002).
