I suppose Dua is just a wish every one has a right.
Allah says in Quran " my laws do not change.", therefore things won't change for whatever reason.
The nations or regions who do not believe in religion do not make Duas, just wishes or expectations for which they believe in working.
Acc to my knowledge our prophet never made Duas. He was a practical man who believed in working as we know it from Islamic history. If some one knows , pls let us know. During messaging he was stoned in Taif city, but he never asked God to punish them. During toughest wars with meccans he suffered like a man but did not ask God for a victory without fight .
