I can't remember the episode title, but the DS9 episode where Sisco and Jake build a solar sailing ship, hit a subspace eddy (or somesuch), and prove the Cardassians completely wrong. How do the Cardassians respond? They celebrate with space fireworks!!!
Space fireworks?!? These are the Cardassians. The only adequate response should have been to destroy the little spacecraft and deny that Sisco ever made it to Cardassia. Celebrating the pie-in-their-face completely ruined the episode for me.
One simple explanation.. politics.
The Cardassians couldn't assassinate a Starfleet commander and his son to keep an unconvenient truth under wraps. Starfleet would have investigated their disappearance, most likely come to the conclusion that they were killed by Cardassian weapons fire and you'd have a huge diplomatic incident.
So all they could do is smile through gritted teeth and play along.
That's politics.. even in our reality politicians do the same.
