All militaries should plan for the worst and plan for the best.
By not planning for the best outcome, one must surmise that the best is nothing more than shooting in the dark, whistling past the graveyard, a rolling of the dice, or blind, dumb luck, because the military doesn’t want to waste their energy and time on something that does not serve their immediate political and financial goals.
Putting out fires to the exclusion of preventing fires, keeps one in a perpetual state of putting out fires.
If you don’t have a plan for the best outcome, then that outcome won’t happen.
