The enemy of my enemy is my friend
An Arab Proverb. In some cases, this is true, as Japan found out when it invaded China . Japan thought that as the Chinese were fighting each other, they would be an easy target - wrong - they may have been fighting each other, but when an outsider attacks, all political issues are put aside for the country's good. This is not always the case; a person I used to know - the same writer I referred to in Author Missing and I shared a common dislike for another author on one site I was on. This made several writers on the site assume we were friends. Nothing could have been further from the truth as I despised him as much as our familiar foe.
