The action action potential produced needs to reach the threshold for the AP to be propagated. If it doesn't reach the threshold, there is not enough Na+ to stimulate the positive feedback system which allows the action potential to be self-propagated. Instead, K+ channels will be opened, and it will enter repolarisation phase, and the AP wll not be conducted.
