That would probably the best approach, I think. Not exactly the stuff great action movies are made of, but if it really should come to this, reasoning* with a sentient and intelligent being that isn't as emotional as a human would be my first try.
*Yes, I know. Didn't work with bomb #20 in 'Dark Star', but they had to have a dramatic end** for the movie, didn't they?
**For an alternative ending, visit the End of Show Department. It is situated at the very end.
