Re: The Wounded - Worf was right!!
A line in The Wounded always creases me up:
"The Cardassians have no honour. I do not trust them."
"They're our allies now, Mr. Worf, we have to trust them."
"Trust is earned, not given away!"
The thing is Worf was right, the Cardassians could not be trusted.
I think you'll find plenty of examples in history where one person says another person/group/nation is not to be trusted. Only to be all but ignored at the time, but proven correct later.
On the continent of wild endeavour in the mountains of solace and solitude there stood the citadel of the time lords, the oldest and most mighty race in the universe looking down on the galaxies below sworn never to interfere only to watch.
