Why was great Britain so vital to Hitler's plan?

Answer 1

good question, i think its because of the fact that Britain happened to be a super power at that time. Britain controlled majority of sea ports and waterways (the most important at that time were Gibralter in Spain, Suez Canal in Egypt, the English channel)

Britain also had dominance over most of Middle East, parts of Africa, India, south East Asia. Australia also happened to be its close ally.

The fact that Britain was leading the allies in the world war can not be overlooked, therefore, its logical that Hitler wanted to bring down the boss himself and prove his might to the world. It wouldn't have been possible for Hitler to control the newly invaded France because Britain kept air raiding parts of it and helping the insurgents. (Remember that Britain had tremendous sympathies with France at that time...)

Had he succeeded, he would have had spread chaos in the British colonies all over the world. This could have resulted in widespread revolts and therefore lesser resources for the allies, and this would have ensured that war with allies would have gotten much easier for Hitler.
