either or 用在否定句中

问题描述:

either or 用在否定句中
When this war is over,no nation will be isolated either be isolated in war or peace.
我选的是 When this war is over,no nation will be isolated neither be isolated in war nor peace.

应该是,
When this war is over,no nation will be isolated either in war or peace.
因为前面已经有no了,如果你再选用neither nor,即构成“否定之否定”,逻辑语义成了“肯定”,与句子本意便相反了.
