Although the last two options might be difficult to merge –Mexico might not want the competition of such a large player as Brazil – they are not mutually exclusive. In fact, Brazil’s leaders have good reason to be flexible: their country needs the access to the Pacific that Peru and Chile offer.
因此乌马拉的拉美备选方案十分有限：委内瑞拉、巴西、或Pacto del Pacífico联合体。尽管后两种方案结合起来有些困难——墨西哥可能并不喜欢与巴西这种大国竞争——但它们也并不相互排斥。事实上，巴西领导人有理由采取更为灵活的态度：他们的国家需要秘鲁和智利所提供的太平洋通路。
