A proviso

This is the G'Nort Proviso to Matthew Yglesais' celebrated Green Lantern theory of geopolitics:

Even if it were the case that sheer American willpower was almost infinitely powerful, the distinction between minimal competence and massive incompetence would be more powerful still. Or in general form: at any given level of power generated by sheer will and determination, the distinction between minimal competence and massive competence in the use of that power is more powerful still.
