Imagine you are stranded in your home with all your loved ones, and you get a call from your "warmonger" president and the matter is urgent; he says "We have received intel regarding a enemy plan to bomb your house in 30 mins. This report is only x% reliable, but we have the exact location of the enemy and we have birds in air that can hit them in 5 mins. This might escalate into a larger conflict, Do you want us to proceed? "
What would your response be? What is the value of `x` at which you will approve of the pre-emptive attack?
What is your percentage to say no lets do not take actions. Because again; with this perspective every single action is legitimate. There is a chance for everything. If there is a weapon that can kill every human on the planet, every country will race to invent it because every country will try to invent it. Every action is valid. Every weapon development is okey, because if you dont, others will. You can kill everyone, because everyone might eventually try to kill you, there is always a chance.
We both know that it is not true. Because by this logic, you wouldn't fire a weapon at someone who is about to stab your wife or child. Because there is a small chance that they will die of a heart attack before they can do it. So it is some value that is < 100%, but apparently that is not good enough for you.
>What does objectivity have to do with the value of x?
It does not have anything to do with objectivity. I thought it to be futile to discuss that since, as you implied, predicting future can't be 100% objective, and thus decisions to avert a bad future outcome always need to be based on subjective decisions.
So this is another question where I want to ask you how you would make a subjective call.
