Do you believe in Nostradamus prophesy about 3rd world war? What is the likely year in your opinion?

I do not believe in any of prophesy but one thing is there there would be a Grate War in near future but not World War. This War would be for supremacy, as USA is slipping out of World Power. USSR, France, Grate Britain, the one time Grate Powers have already gone from the list of Power full countries.
