Guten Tag, Britain. Look at your Navy, now back to me, now back at your Navy, now back to me. Sadly, it isn’t me, but if it had a fleet of U-boats, it could sink ships like it’s me. Look down, back up. Where are you? You’re in a minefield off the Orkneys, rolling in the deep with Kitchener. What’s in your hand? Back at me, I have it. It’s a torpedo lodged in the hull of that ship you love. Look again—that ship is now on the ocean floor. Anything is possible with unrestricted submarine warfare. I’m off your coast!
