"National Security" has always been the ultimate unfalsifiable accusation.

Only those who have access to the underlying classified information can legitimately make the argument. Those who don't have the same access must trust those who do.

The system breaks down quickly when the former group gets everyone into a war because they failed to vet the underlying intelligence or purposefully misconstrued the intelligence or they just moved the goalposts of "national security" to include preemption.
