I'm of the strong belief that world leaders involved in pissing contests should settle them 1-on-1 (or even many-on-many) in a mano-a-mano royal rumble*, instead of manipulating hundreds of thousands / millions of people to their death and costing billions on weaponry and infrastructural damages, in order to win a pissing contest on their behalf.
*Heck, if you televised it I'm sure it would make excellent pay-per-view
