How was Neville Chamberlain involved in World War 1?

Neville Chamberlain did not play a direct military role in World War I, as he was primarily involved in domestic politics during that time. However, he served as the Minister of Defence during the latter part of the war and was responsible for munitions production and coordination of military resources. His experiences during the war influenced his later political decisions and his approach to international relations, particularly in the context of appeasement during the lead-up to World War II.
