[Platapus]

To the optimist, a compromise is the result where both sides win
To the pessimist, a compromise is the result where both sides lose
To the pragmatist, a compromise is the result of doing the best you can with what you have.

All three are correct.

Capitulation only works in an environment where these is a quid pro quo exchange.

I allow you to get everything you want in this area and you agree to give me everything I want in another area. Unfortunately, that only works when each side does not care that much about one of the issues.

One of the skills for a good negotiator is being able to recognize that which the opposing party is willing to negotiate and that which the opposing party is not willing to negotiate. They can then focus on the possible instead of wasting time on the improbable.

There are times, rightfully or not, where the concept of "everything is negotiable" may not apply. That's when you reach an impasse and that's when the skill of negotiation becomes apparent.
