United States Foreign Policy, Rule 1 (suggested).
7.85.36. In the absence of a clear and present danger to national security, the United States shall not take action to topple any foreign dictator or government, unless and until: (a) the US intelligence services and military are 100% certain what comes next; and (b) we are fully prepared to take steps to implement the transition.
The rationale behind this new rule?
In plain English – An evil dictator who leaves the USA alone, may actually be preferable to a ‘country-turned-Mad-Max-sequel’ filled with people trying to kill us all the time.
