... Peter, not membership status! <g>

In any event, your observation is essentially incorrect. There has not been a major war in modern history in which all of the participants on any side were all part of the same army. Certainly not in this century -- and in the last century, perhaps only the American Civil War. Even going back to the middle ages, "armies" from a variety of countries or regions often joined together to fight similar composite armies on the "other side".

Which is all beside the point, which remains valid -- that is, the bigger the organization, the greater the need for local, rather than centralized, control.
