Why Isn't There a Debate about America's Grand Strategy?

“The United States needs a new set of ideas and principles to justify its worthwhile international commitments, and curtail ineffective obligations where necessary,” argue Jeremi Suri and Benjamin Valentino, in the introduction to their edited volume Sustainable Security: Rethinking American National Security.

How Submarine Warfare Was Changed Forever after the Sinking of This British Ship

In October 1939, illuminated by the northern lights, the German submarine U-47 threaded its way through sunken barriers and slipped into the British anchorage at Scapa Flow, a 125.3-square-mile natural port off the northern coast of Scotland, in the Orkney Islands.

Penetrating the anchorage had long been an unrealized German dream, one that U-boats had attempted twice in World War I; both times they had failed. One U-boat had been rammed and run aground and the second destroyed with all hands.

In 1942, U.S. Marines Launched a Raid from Submarines Straight out of an 80s Action Movie

On a stormy night, U.S. Marines set off secretly from submarines to assault a remote island base. They are led by a controversial commander with radical new ideas. And the son of the sitting U.S. president is one of his officers.

The Makin raid in 1942 might seem to have the implausible plot of an action movie—and in fact, one year later it would become one! But it was a deadly real for both the American and Japanese troops involved. What was arguably the first combat operation ever undertaken by a U.S. military special forces unit nearly ended in complete disaster.
