The close-versus-distant label can obscure the more important question of how coercion is applied. Britain's First World War system operated far from German ports but still controlled access to maritime supplies. German campaigns against Britain attacked ships and limited arrivals, yet did not exercise the same control over the trade routes. In this interpretation, the German effort was siege through maritime attack rather than blockade in the stricter sense used throughout the video. Norway and continental access also show why land connections can weaken an otherwise effective distant cordon.

British distant blockade versus German submarine siege
The First World War British system controlled trade routes from a distance, whereas German attacks in the world wars tried to destroy shipping without establishing comparable control over the routes themselves.
