Building the Kill Web: GCC-Israel Security and Deterrence Architecture

03/21/2026 By Robbin Laird If the first strategic challenge is to define the demilitarization objective and the coalition that enforces it, the second is to build the kill web that gives that coalition real deterrent teeth. Deterrence in the post-war Middle East cannot rest on declarations or episodic deployments. It requires persistent, integrated, and credible architecture or security, deterrence and kill… Read more »

The “Super B 1B”: Hypersonics, Kill Webs, and the Revival of a Legacy Bomber

03/20/2026 By Robbin Laird The “Super B‑1B”: Hypersonics, Kill Webs, and the Revival of a Legacy Bomber In earlier work, I argued that hypersonic weapons would only become strategically meaningful when embedded in a wider kill‑web construct what my colleague Ed Timperlake described as the evolution of S‑cubed, where speed, stealth, and situational awareness are fused into a 21st‑century strike enterprise.

From Barbary Pirates to Iranian Mullahs: Here Come the Marines

03/17/2026 History rarely offers the same strategic irony twice. In 1805, a small detachment of U.S. Marines marched out of Alexandria across the North African desert to put steel on the “shores of Tripoli,” breaking the grip of Barbary pirates who believed they could hold American commerce and citizens hostage at acceptable cost. In 2026, Marines are heading eastward again, this… Read more »

China’s Djibouti Hinge and the Persian Gulf: Rethinking Access, Not Just Bases

03/17/2026 By Robbin Laird China’s presence in Djibouti has usually been read through the familiar grammar of bases and bastions, a forward military foothold that extends PLA Navy reach toward the Red Sea and the Persian Gulf. That reading is not wrong, but it is incomplete. Djibouti matters less as a standalone outpost and more as a hinge in a wider… Read more »
