Evil wizards
From Speakeasy
Evil Wizards that teleport into another country is an example of "out-of-the-box" thinking on the part of emperor_palpatine , who also often uses computer strategy games in his analysis of world politics and warfare.
While the origin of the idea (and the board it was first proposed on) is still under dispute, it first came to light on Speakeasy in this thread October 28th, 2005 at 2:06 pm.
Ever since, the teleporting Evil Wizard theory has been mooted about by many members as an explanation for or potential solution to global problems.
According to Sainte-Marthe, who first popularised the phrase, "an evil wizard is a deus ex machina used to give any outrageous hypothetical or explain any highly unlikely action which could be theoretically possible due to the intervention of a mythical magician."
