Yes, everyone wants a peace, but some want a piece. If a country invaded us that was militarily our equal, would we want to give up the west coast in hopes that said country would honor any peace deal? What if that country had already violated a previous peace deal with us and just invaded? What if that country had a history of breaking peace deals and invading sovereign countries? You can't have peace through appeasement. We should have learned that from the first two world wars.
