I do believe the geopolitical stability of the past over 80 years since WW2 has already ended or more so is going to evolve into another geopolitical reality. The world is moving towards a multipolar world and as such that means there going to be conflicting interests sooner or later among the great powers such as US, Russia, China, EU, India, etc. The US is little by little losing the trust of other countries governments that depend on the US. And since the US foreign sphere of influence is waning then some other power may or will come in to fill in the power vacuum. Imo of course no knows the future, but something most definitely feels like it will happen in the next 20-50 years such as a major war possibly even WW3, exacerbated by climate change, natural disasters, economic collapse, mass famines, massive die-offs, biological collapse, genocides, a lot of others unknown crises I bet fuck.
