Ruling Garchomp POP9

Ok, so this question pertains to his second attack, Jet Sword.

It reads:

Jet sword - 100

Discard 2 Energy attached to Garchomp and this attack does 10 damage to each of your opponent's Benched Pokemon. (Don't apply Weakness and Resistance for Benched Pokemon.)

Do you always need to discard two energies or is that just for spreading to the bench? I'm convinced it is always, but someone thinks otherwise.

Since it reads "Discard 2 energy..." and not "You may discard 2 energy..." the discard is mandatory. If you can't discard, the attack would do nothing.

Thank you. Thought as much.
