In order to effectively counter any potential material replenishment to Germany from around the world, Britain-France-Australia, after sustained deliberation, finally decided to implement a rather overbearing policy, which is the unlimited submarine warfare policy.
The so-called unlimited submarine warfare policy is primarily aimed at using submarine attacks to effectively prevent external resources from being exported to Germany.
The range of unlimited submarine warfare covers the entire Atlantic Ocean and the Mediterranean Sea, and it can be said that the British were determined to eliminate any possibility of countries transporting resources to Germany.
Of course, such actions are bound to cause collateral damage.
