A Pretext (n.) for war can be manufactured: stage "spikes of activity" until the enemy hands you a casus belli — and if he refuses, invade anyway.
Pretext (n.) can switch overnight without anyone noticing: when the Soviet Union fell, the strangling of Cuba became a matter of sincere dedication to democracy.
Pretext (n.) for Cold War intervention was Soviet meddling; the reason, often frankly admitted, was turbulence from within, largely for economic reasons.
A Pretext (n.) can be changed daily when the goal never changes: we will do what we choose, giving whatever reason happens to be on hand.
Pretext (n.) can be manufactured: a liberal adviser proposed luring Castro into a raid on Haiti so that "the moral issue would be clouded."
