I've always been interested in military history, the theory of warfare, command, and the power and implementation of authority.
Here's a list of some of the ideas I've been studying over the years; of course I really should get around to reading von Clausewitz and Machiavelli's 'The Prince.'
the theory of disproportionate retaliation
the avoidance of defeat by dictating and imposing your enemy's terms of victory
'never explain, never apologise, never compromise'
the theory of asymetric warfare
the practice of torture should never be undertaken to extract information; but always to modify behaviour
a threat is not a threat unless you are prepared to carry it out
my enemy's enemy can still also be my enemy
keep your friends close, and your enemies even closer
target/enemy selection and acquisition
doing the unexpected can always be expected and countered, but its effects can't
in a hostage situation the mission of any special forces operation is to kill the kidnappers/terrorists...the rescuing of any hostages is merely a bonus
'he who has nothing, has nothing to lose by his actions'
the law of unintended consequences
'be careful what you wish for, it might come true'
'if it ain't broke, don't fix it'
if you're powerless, being right is never enough
sometimes, Murphy's Law doesn't apply
