- If we plan an action with the intention of giving ourselves, say, three decades of control over some territory's resources, then we should think through how that control will actually be realized for those three decades.
- If the plan is for a nuclear strike, which will leave behind radiation poisoning some region for, say 50,000 years, then we should take the time to ask if we really want to sacrifice that territory for that long.
In other words, be clear on the distinction between a debate over whether or not a plan is justified and the process of thinking through a clear answer to the often overlooked question:
If you cannot think it through satisfactorily for the whole period over which your action will have an impact, then you do not know the outcome of your action and to undertake it would be irresponsible, perhaps suicidal.
What makes you think your plan will actually work for the
whole time period over which you want it to work?
