Maybe many people have no concept of national contingency plans, feeling like when the country handles big disasters or unexpected events, there's nothing special, just similar response measures, not like there's any plan or arrangement.
But in fact, for most possible situations, small countries may indeed have no plans, but for major countries, their contingency plans for disasters and various unexpected events are far more than just one.
Many times, what you think is commonplace may very well be the preparation a country has made for certain events.
Take the familiar Federation as an example. The highest leader and commander of the three armed forces is their President, who not only holds the Federation's highest power but also the most important nuclear launch codes.
