Why does chamberlain suggest appeasement and under what conditions would he fight?

Neville Chamberlain suggested appeasement primarily to avoid another devastating conflict like World War I, believing that satisfying some of Adolf Hitler's territorial demands could maintain peace in Europe. He operated under the belief that the grievances of Germany could be resolved through negotiation rather than military confrontation. Chamberlain indicated that he would consider fighting only if Germany's aggression directly threatened Britain or its allies, or if diplomatic efforts to resolve tensions failed completely.
