We humans (homo sapiens) are wild creatures, all have their pride and ego . They all have their own version of nationalism, we choose to fight among each other or form alliance to make our life easier (of course for selfish reasons). some are greedy and backstabbers, some might be more loyal. Humans are ruled by humans, that are called leaders, they are good at political speeches and making empty promises, desperate at winning election, true leaders are those who are with their humans, navigating through shaky times and front flipping towards success, not the ones who hide and run away like a crying baby. With great power comes with great responsibility.
“If you want a vision of the future, imagine a boot stamping on a human face — forever.” — George Orwell
Do we really wants to fight each other?, yes but you would say no, it is the human nature, we cannot change that in a million year, we humans with land collectively called country , will forever have the thirst for revenge , superiority complex, pride ,ego, and spread their seed like an ant colony with leader as their queen.
