Is it safe to assume that when a country is still young and full of energy, it prefers to take more risks and expand? Is it safe to assume that when a country is old, it prefers to play it safe? What would make a country young? In my opinion, a country is young when it got a huge amount of people that are between the age of 12 to 27. Why? These young people can and will be able to lead their country in the direction that they want since the older generations have to pass their torches eventually. Furthermore, a young country got enough young soldiers to wage a war! This will not be that important when a country decides to employ more AI robots and automation in a war, but in its presence, human soldiers are still being mainly a deployable asset for any combat situation. Human soldiers are still driving and flying war machines and drones.
A small country with a small population and not enough economic power and technology might not be a threat to bigger countries even though such a small country may have a huge population of young people. It would be a different story for a huge country with a huge population size because such a country can deploy young, energetic human resources to grow and expand the country's multifacet powers. It's even more dangerous when such a country got a really large, energetic, young population. Why? Assuming we're not going to use automation anytime soon, and so if I'm running such a country I would think about capitalizing on the power of a huge young population to grow and expand my country. For example, I wouldn't be so timid in launching a war against a hostile country.
I have a feeling that even when automation gets to be in the driver's seat, an unrest young population of whatever country could still drive their country into a more risky proposition than otherwise. After all, logically if they're not taking risks when they're young, what would make them excited when they're old? If my theory is correct, I wonder could we see a lot more wars and deaths if the world's population is full of young people? Of course, I could be wrong in a way because older people do take risks too! What if a small group of older people can make and drive the agenda that make use of the aggressiveness features of the young population? Nonetheless, I still think the huge population of young people still is an important element in the equation for taking risks. Without the huge, energetic young population, nothing will happen even if the small group of old people wants to wage a war!
