1/ As we fire up our grills for Memorial Day and look forward to July 4th when we will celebrate the 250th birthday of this nation, we should all pause and reflect. 2/ What do we the living owe those who gave their utmost to secure the freedom that we enjoy every day?

Freedom that we have become so accustomed to that most of us essentially take it for granted.

As one of my great mentors Henry Kissinger frequently noted, too many Americans imagine that “peace is the natural condition of mankind.”

In fact, as the bumper sticker version reminds us: “freedom is not free.”

1/ A Four-Star’s History Lesson on the Iran War

A must-read summary of a great listen: see @nytimes @DavidAFrench's conversation with former commander of US Special Forces in Afghanistan and Iraq Gen. Stanley McChrystal.

nytimes.com/2026/03/23/opi… 2/ To successfully meet the challenge the US currently faces in Iran, McChrystal recommends starting with “strategic empathy”: asking how the events occurring today look through the eyes of our adversary. (In the security studies canon, strategic empathy is an antidote to Americans’ natural “strategic narcissism” that understands events only through our own eyes, assumes others see the world as we do, and expects them to act only in response to our initiatives.)
