"However much we may sympathize with a small nation confronted by a big and powerful neighbours, we cannot in all circumstances undertake to involve the whole British Empire in a war simply on her account"

This quote by Neville Chamberlain is describing the idea of Britain's participation in a war on behalf of a little country. Chamberlain is expressing sympathy for the little nation, but is also making it clear that Britain can not constantly be anticipated to involve the whole Empire in a war merely since of the small country's plight. He is stressing the importance of thinking about the consequences of such a choice, and the potential dangers to the Empire as a whole. This quote shows Chamberlain's belief that Britain ought to not participate in a war lightly, which the decision to do so must be made with cautious consideration of the possible effects. It also shows his commitment to safeguarding the interests of the British Empire as a whole.
