We, the undersigned, do hereby inform you that we are in complete agreement with Iranian President Rouhani’s recent characterization of you as “mentally disabled”. Furthermore, we wish to advise you that, should you order U.S. military forces to attack any nation, or cause harm to the people of any nation, such actions would inspire neither our respect for you nor our fear of you. Any such orders or actions by you would, instead, serve only to confirm our unilateral belief that you are an ignorant, insane, malevolent, megolomaniacal moron who deserves to be forever incarcerated in an Institution for the mentally unstable and criminally insane.
The Leaders of Every Nation on Earth (with the exception of the U.S.ofA.)
P.S. Definitions of words you do not understand can be found in the O.E.D.
