Some how at the end of WW2 America rised to superpower status and foolishly promote their NAIVE CHILDISH IGNORANT values of Humanity Peace Freedom n Democracy.
Blindly blanket granted security and flase INNOCENCE to all human being, and embraced the enormous mistake of Co-Existence in Peace, like a 3 year old saint saving entire world from NECESSARY ELIMINATION BALANCE and Carnage.
To satisfy coexistence in peace UNPRECEDENTED ENORMOUS AMOUNT of RESOURCES needs to be PLUNDERED from planet earth, explouting scientific engineering n industrialized methods, with GREED and FOOLISHLY WRONG Assumptions that planet earth could supply and endure UNLIMITED EXPLOITATION OF VITAL RESOURCES!
They never knew that it's was an efficient mass suicide and driving man towards total extinction, and destruction of entire living system on earth.
Now they know that their crap can not be reversed nor undone, they seek another fucking planet to migrate and abandon the hopelessly dying earth.
About 70 years this mistake came to irreversible dead end. Billions of man kind face crisis of total extinction. Many other spices on planet already extinct.
Man obeyed planet's natural rules of servival and competition / elimination, from caveman ages until WW2. Population was kept sufficiently low all those times. No foolishly greedy ideas of peaceful coexistence, until the last 60~70 years, the landmark was US led forming of United Nation with idiotic constitution to enfore global peace.
That marked the beginning of mass suicide towards total extinction.
