Fundamentalist groups become more fanatical, and nations, agencies, militaries, and political parties become more repressive and authoritarian as the promotion of adversaries drags on.
It is argued by some that the modern-day guerrilla tactic of suicide bombing emerged from conditions in which one or more promoting adversaries relationships developed.
However, that is not necessarily their actual strategy because they have deliberately made their propaganda even more utterly unconvincing than it already is; they make sure that the population is constantly exposed to obvious historical revision and introductions to Goldstein's political views for the sake of testing the population to provoke any potential dissidents into dissenting so that potential dissidents can be caught.
The tactic is dynamically similar to certain publicity techniques and so can be used by individuals and products seeking to gain or concentrate power or wealth as well.
The promotion of adversaries has also been parodied most recently by Stephen Colbert on The Colbert Report in which Stephen's brand of Ben & Jerry's ice cream (AmeriCone Dream) is pitted against Willie Nelson's brand of Ben & Jerry's ice cream (Country Peach Cobbler).
