Can we have competitive evolution without primitive war?

On this Memorial Day I was thinking of how Raymond Cattell, with his fearless eye, called war a degenerate form of competition, yet he questioned mankind trying to rule out all competition in a hedonistic pact.

Whether we like to admit it or not war has been a test of the power of group survival, but it would be far better to see a higher level of testing between groups through cooperative competition. Yet realism says that cooperative competition in the world would still need to be backed by force, since we are an imperfectly evolved species. Power vacuums won't control invading power.

If we care about advancing in evolution we need to somehow rationally allow for expansion and contraction, that is, the evolution of groups. We can't block evolution, we will have explosions if we do. It will greatly help when we all can see the full importance of distinct groups having their own regions, virtually their own ethnostates, no matter how small. Competition within the same species is always greater than competition between different species, each species tends to find its own niche. Separation is vital for peace. Each group can then get on with the challenges of evolution within nature itself. The United States of America, my country, made a start in its original Constitution, with its separation of powers and states.
 

The idea is to have all groups, all nations, jointly exploring and advancing in evolution without primitive wars, and, yes, we can suppress war without suppressing evolution.
