I agree with that, completely.
I'll be controversial and say that it depends on a case-by-case basis (what's at stake, what's plausible, what enforcement will there be of the new status quo). If there are
long-standing problems that can be resolved without war and which can produce guaranteed settlements, why not?
There's a difference between appeasement and what you're describing.
What you're describing is a careful, thought-out, most likely mutually beneficial agreement/negotiation.
Appeasement, on the other hand, is the giving in to another power in the hopes
that they'll accept it and not cause further trouble.
