That is an (not "the") interpretation of "Shantih."  But the lines above that are about violence, chaos, and murder. Moreover, Cleo Kearnes has pointed out that the full ending of the Upanishad starts with "Om," and Eliot omits it (though we know he studied them). 
 
So you are free to interpret one line as shaping all the rest, but that interpretation is not "what the lines say": it is one reading of very mixed lines.

Interesting to see that presentation again.
They end it with a very positive tone, but then that's what the lines say.
I suppose one could render them in an ironic way, but that would seem rather forced.
