What argument does Churchill make in this speech?

Do not suppose that this is the end. This is only the beginning of the reckoning. This is only the first sip, the first foretaste of a bitter cup which will be proffered to us year by year unless by a supreme recovery of moral health and martial vigour, we arise again and take our stand for freedom as in the olden time.

Reaching an agreement is the only way to end Germany’s aggression.

Avoiding a war at all costs is the only sensible stance in this situation.

Giving in to Germany’s demands will only lead to more demands down the road.

Going to war is the best approach to solving most diplomatic problems.
