I’m pleased to share my review of Roady & Preston’s recent histories examining the roots of national security in FDR’s New Deal. My thanks to the @Lawfare editorial team for their guidance. And my thanks to @mbrenes1 for his support lawfaremedia.org/article/how…
Replying to @seanmcase
@seanmcase reviews “The Contest Over National Security" by Peter Roady and “Total Defense" by Andrew Preston, which both trace the faults with our current understanding of national security to the New Deal, but tell quite different tales with different characters.

I first read The Talisman when I was a teenager, and the story displayed the power of portal fantasy. And then Black House expanded the story’s scope into a detective thriller. I feel as if I’ve grown up with Jack Sawyer - I’m thrilled to see how his story ends
My new one, OTHER WORLDS THAN THESE (T3), is published today. It's the final book of the Talisman trilogy, co-written with my old buddy, Peter Straub. As DJT would say, thank you for your attention in this matter.

This is a statement performance from the #Knicks, in a spot where everything should have pointed the other way. Both ends of the floor. This team is really good.

What a stellar lineup! I’m thrilled to see Rosenberg’s “Financial Missionaries to the World” and Preston’s “Total Defense” at #3 and #4, especially since I recently recommended both to a friend for his professional reading. All are well worth reading & considering
Bloomberg News asked Daniel Immerwahr for his top five books for understanding Trump’s dreams of empire: #1-3

Given the impending expiration of the New START Treaty, it’s worth revisiting what in all likely will be lost - a stable nuclear order on the international scene
U.S. allies and partners are striking nuclear deals with one another to guarantee their security without the United States. @RebeccaLissner and Erin D. Dumbacher explain how this presents daunting new risks to global security. foreignpolicy.com/2026/01/05…

Would pair well with Mark Twain
The guidebook writer Rick Steves believes in the transformative power of travel. “I want to go home a little bit different, a little less afraid, a little more thankful, a little better citizen of the planet.” Read or listen to more on The Interview. nyti.ms/4iDq4NV

I’m so pleased to share my @HDiplo commentary essay "Henry Kissinger and the Angel of Applied History!” From fever dream to reality, or, “so you want to say Kissinger was a historian…” My thanks to my @ISSYale community for the support & encouragement issforum.org/commentary/h-di…

I’m thrilled to attend the upcoming ISA 2024 with dear friends. If you find yourself in San Francisco, come on by for our panel on historical actors and their approaches to IR. Or, as I like to think of it, “a group of historians walk into ISA…”

Annelle Sheline crafted a public statement of dissent that’s reminiscent of Elizabeth Shackelford’s documenting of the dissent channel’s shortcomings at State. It points to the alarming trend of silencing internal dissent within U.S. federal government systems
Annelle Sheline writes that she decided to resign from her position at the State Department given US policy toward Gaza. "Whatever credibility the United States had as an advocate for human rights has almost entirely vanished since the war began." cnn.com/2024/03/27/opinions/…
