Not unless those bad human characteristics are going to create attitudes that are going to cause more divisions, conflicts, catastrophes, and possibly more Wars. If there is no change in the status quo as far as how the World thinks and operates and if Humanity stays on the same course as before as far as continuing to cause more damage to the environment, sooner or later our World will self destruct as it is under threat from so many different fronts. The window of opportunity to take action is small and is closing fast, it will be ashamed if humanity with all it’s intellect, skills, technologies, experiences, and intelligence fails to save itself. Any logical prediction or forecast of the many different possible outcomes for our World would most likely show that the survival of humanity and this planet both require immediate and meaningful intervention and changes in our ways.
Isolationism might have its advantages and can put one country or continent temporarily ahead as it unifies people against outside threats, but since every continent is capable of damaging and destroying the World on its own it really doesn’t matter how far you advance through isolationism if people on the other side of the World can undo all your success and achievements due to their ignorance or animosity. For the humanity and this planet to survive it requires for all people to control and contain those bad characteristics that prevent them from coming together in a positive way to do some good for the World. We have to accept the fact that no one can save themselves alone without saving the whole World. IMO
