Just look at history and recent political events.
The world is broken up to 196 countries, never mind the myriads of tribal sub-groups in each individual country.
It is the same species, on the same planet, easily intermixable with each other as immigration statistics show.
However, as long as individuals carry their tribal identity, instead of their species-identity, with them, there will always be wars, massacres and atrocities.
The ‘leaders’ take full advantage of this by sicking one tribe against the other, convincing their ‘subjects’ that the ‘other’ is subhuman, evil, dangerous, out to get you.
All this would be impossible if people realized that we are, for all practical purposes, one tribe: we want to live our limited life on this planet, in peace, being productive, looking after our families and friends.
Until people realize that they are primarily human beings, all in the same boat, instead of members of a besieged sub-group somewhere defending their territory tooth and nail, they will be always at each other’s throats.
And our masters laugh all the way to the bank.

Tribe within a tribe
Tribe within a tribe within a tribe,
a maddening nesting of Matryoshka,
who can keep track of the obligation
one has to each generation.
I must be a good husband, a good citizen,
a good employee, a perfect gentleman,
and when my tribe tells me to fight
I have to go and bleed in the night.
Why can’t we just have only one tribe
that all of us belong to -- dammit
the tiger has only one kind of stripe
there is no reason to complicate it.
We are all human, on this forsaken planet
stuck in the same boat on the ocean,
if we keep fighting tribe against tribe
we will never have a moment
of peace, when we can love each other…
…forget the stupid tribes and learn to live together.
