^Wow! That's cynical. I'm not sure that it squares with Kirk's embrace of the ideals of the US Constitution in Omega Glory.
Funny thing about Sarek: they play fast and loose with his position. In Journey to Babel, he's the ambassador for
Vulcan. In Sarek, he is a Federation ambassador from
Vulcan. The idea that Vulcan might need an ambassador doesn't trouble me: the separate states of the Wilhemine Empire conducted diplomacy with other German states as well as other countries. What I find more troubling is that he might advocate for both Vulcan and the Federation, depending upon the mission.
