Well, yes.
A certain religious outlook desires to prompt the return of the 12th imam, or something. Of course I don't know the details at great length, but there may be some ideologies that may find the final apocalypse a desirable outcome. If a leader of a country with access to nuclear weapons had such tools, yes it is conceivable that that would be a desirable goal.
So if there is such a person running around, yes, I think they would be "silly enough".
