> The point is that surrender is something that has to be negociated.

It actually doesn't have to be negotiated, one side can simply make a demand for surrender with their terms and then apply military pressure until capitulation. This is largely what happened with Germany/Japan in WW2.

If it's clear the current negotiators/leaders will never surrender then there is arguably no benefit in keeping those particular negotiators/leaders alive. Once an organizations leadership tree is wiped out a few levels deep there's a decent chance you will get negotiators/leaders that will eventually capitulate to the demands(i.e. like what happened with Hezbollah).
