在历史上，邦联早晚都会变成联邦（就像在美国、德国和瑞士发生的那样 ） ， 或者在离心力的推动下，分裂开（就像1958年建立的阿拉伯联合共和国，它在三年后分裂成了埃及和叙利亚 ） 。
Historically, confederations sooner or later either become federations (as occurred in the US, Germany, and Switzerland) or, pushed by centrifugal forces, split up (as with the United Arab Republic, established in 1958, which split three years later into Egypt and Syria).
