Unshakable Resolve and Kitsune Den

a question came up in a recent game regarding Unshakable Resolve and Kitsune Den

setting: there are no dishonorable personalities in play (but there are honorable ones)

question: can i still use Unshakable Resolve or Kitsune Den's abilities? the targeting part of both cards would fail, ie no dishonorable persons, but would the other parts still occur (ie gain honor or force) or am i wrong (which i suspect i am)? there are no constraint costs (words between colons?) that specify a dishonorable peep, so it makes me unsure what the rule would be.

Unshakable Resolve Open: Rehonor your target dishonorable Personality. While he is opposed this turn, he has a Force bonus equal to his Personal Honor. If his Personal Honor is 4 or greater, gain 1 Honor.

Kitsune Den Political Limited: Destroy this card: Rehonor one or more target dishonorable Personalities. Gain Honor equal to the highest base Personal Honor among them.

thanks for your time

Without dishonorable targets, you cannot legally announce those actions.

Good Faith Rule (Emphasis Mine): "When an action is announced, the player must be able to target all required targets, meet all conditions of the action, and pay all mandatory costs, to the best of his or her knowledge."

Required Targeting: "An action’s required targets consist of anything that is targeted by the player taking the action in the action's constraints or effects, using the word “target” or “targets,” unless the targeting is explicitly described as optional."

There are no dishonorable personalities in play (but there are honorable ones). can i still use Unshakable Resolve or Kitsune Den's abilities?

No. Those are mandatory targets.
