Depolarization = ion channel opening?

Hi huys, I have a problem with this statement: "Action potentials are formed when a stimulus causes the cell membrane to depolarize past the threshold of excitation, causing all sodium ion channels to open."

Isn't the cell membrane depolarized BECAUSE the ion channels open?
