the question is :

would a "visit and search" policy be possible for the Germans?

(this is about the unrestricited submarine warfare)

I thought yes but then ... I don't know
Another source said that it was not possible

It wouldn't be possible for the allies to use the "visit and search" policy for German submarines. The policy states that only commercial vessels can be searched. Submarines were only used for the war.

But, the visit and search policy benefited the U.S.

So, would it not matter if Germans searched a neutral merchant ship

The Germans could search a neutral merchant ship -- but I doubt if they used submarines for that.

It saids that U.S. wanted German to use the visit and search policy on neutral merchant ships

thanks

You're welcome.

To determine whether a "visit and search" policy would be possible for the Germans during the time of unrestricted submarine warfare, we need to gather information about the historical context and policies implemented during that period.

During World War I, Germany employed a policy of unrestricted submarine warfare, which involved targeting and sinking any enemy merchant or passenger ships without warning. This policy was in direct violation of international maritime laws that were in place at the time.

A "visit and search" policy, on the other hand, involves stopping a ship and conducting an inspection to determine if it is carrying contraband or posing a threat. This policy requires adherence to international laws and agreements regarding maritime warfare.

Given that Germany engaged in unrestricted submarine warfare, it suggests that they were not following a "visit and search" policy. Instead, they relied on the element of surprise and the sinking of enemy ships without prior warning.

To get a more detailed and accurate understanding, it would be beneficial to consult reputable sources such as historical records, scholarly articles, or books that focus on the specific policies and actions of Germany during World War I. These sources can provide a comprehensive analysis of the German approach to submarine warfare and whether they implemented a "visit and search" policy.

Remember to critically evaluate the credibility of the sources you consult and consider various perspectives before forming a conclusion.
