Q1: When the opponent's Digimon attacked, I tried to delete another Digimon with this card's INHERITED effect, but the other effect did not delete the Digimon. Can I terminate the attack in this case?
No, attack cannot be terminated. The "by letting" condition means that if the content cannot be executed, no further processing is possible. In this situation, if you cannot let it delete, you cannot terminate the attack.
Q2: What is the effect of "terminate attack?"
If this effect is activateD, the current timing becomes "at the end of attack". For example, if this effect is activated at the "attack declaration" timing, the timing becomes "attack end timing" from the "attack declaration" timing. The attack will not progress to "counter timing" or "block timing," and the attack will not be completed.
Q3: Can a Digimon attack that is not affected be terminated by a "terminate attack" effect?
Yes, you can terminate the attack. The effect of terminating the attack does not affect the attackING Digimon, since the effect is to change the timing.
