At the cost of dragging GB into the war?
GB didnt have an army at that time, dragging a country without an army into a war is a non factor, they had industry to build one over a period of 2-3 years which they did but in 1939 they'll be fighting with their d*cks.
Not so sure about that. I always thought Hitler wasn't really interested in a war with the Brits.
Only as long as Brits didnt bother him, war with UK was inevitable anyway, there could be only one maritime power in Europe and Hitler wasnt big on second places.
