Oh I dont know, a German navy would be really useful in the Persian Gulf right now.
You think? I think having no vessel would be less useless than having a German vessel. Do you expect the Germans would do anything but look unhappy when the Iranians capture a ship? Can you imagine them shooting down a helicopter or sinking a boat because it might intend to capture a ship?
I'm sure they would do a great job, with great competence. If they were allowed.
