Is Just War Theory Obsolete? (E143)
Is Just War Theory Obsolete? (E143) Sep 6, 2026 511 Is Just War Theory still relevant to war and war fighting in the world today? Are the criteria of Just Cause, Right Intent, Legitimate Authority, and Proportionality, and Last Resort tools to restrain nations from going to war, or have these principles been twisted into excuses for going to war. This is part of the argument Pope Leo XIV makes in his recent Encyclical, Magnifica Humanitas, in which
Just War and Atom Bombs (E142)
Just War and Atom Bombs (E142) Aug 31, 2026 805 Every August and September, the U.S. atomic bombing of Japan in 1945 seems to be a topic of discussion. This year, I decided to take that on and place it into the Just War framework, specifically jus in bello, or justice in the conduct of war. Just War Theory is a recurring topic in this podcast series. I believe that this framework is critical as a restraint on war and to establishing a just and
Is Hizballah a Mercenary Organization (E141)
Is Hizballah a Mercenary Organization (E141) Jul 16, 2026 1899 The common definition of a mercenary is a soldier paid to fight in an armed conflict for a country that is not his or her own. The terrorist organization Hizballah operates in Lebanon, fighting against Israel, with financial, material and organizational support from Iran, and frequently under the direction of the Iranian Revolutionary Guard Corps. Under the common definition, could Hizballah be co
War Is Irrational (E140)
War Is Irrational (E140) Jun 16, 2026 618 Is war rational? The great philosopher of war, Carl von Clausewitz, was a product of three schools of education: the classical tradition of Aristotle, the enlightenment philosophers such as Kant, and the practical experience of Napoleon. Each of these three challenged and opposed the other two. His work, On War expresses this tension and opposition. In his effort to develop a comprehensive theory
The Rational Actor Model (E139)
The Rational Actor Model (E139) Jun 9, 2026 633 Since at least the 1940’s, policy and strategic thinking uses the so-called rational actor model in determining what competitors and partners may do, how to respond to them, and how they may react in return. Even considering variations to that model to explain less than optimal choices by these actors, there appears to be enough irrationality by state and non-state actors to call into question whe
Wars of Choice? (E138)
Wars of Choice? (E138) Jun 1, 2026 616 I haven’t posted for a few weeks mostly because the current armed conflict with Iran poses a lot of questions that I don’t have answers for. One thing I might have an answer for is the question about wars of choice. Recently, this term is used in a way that implies that this armed conflict is illegitimate or unethical. Like many terms used by any faction with intended political impact, the term is
Cyber-Mercenaries (E136)
Cyber-Mercenaries (E136) May 14, 2026 1000 Any quick net search for the term “cyber mercenary” will result in dozens, if not hundreds of entries. These concerns largely focus on the effect these persons or entities have on personal freedoms, economic activity, and the ability of hackers and States can work together to undermine human rights. What about cyber mercenaries and warfare? Can – or do – real mercenaries of the cyber domain of war
Ceasefire? (E136)
Ceasefire? (E136) May 1, 2026 640 As I post this, the cease-fires in Lebanon and Iran are still holding, and much longer than I expected. We usually think of cease fires as a good thing, enabling humanitarian activity and at least pause the death and destruction. That is not, however, the purpose behind any suspension in fighting a war. In this episode I examine the real reasons for most truces or cease fires, explore probable mot
What is a War Crime? (E135)
What is a War Crime? (E135) Apr 18, 2026 617 Every time the United States or Israel use military force, there are immediate claims that those military forces are committing war crimes. I also note that such claims are never made about the opposing side, whether that is Hamas, Hizbollah, Houthis, Iran or any other state or non-state armed group opposing Western armed forces. It also seems that there are voices that insist than any military op
Winning and Losing (E134)
Winning and Losing (E134) Apr 12, 2026 481 The United States is in yet another war. The usual pundits say that we cannot win while others say we have already won. The same people seem to say nearly the same things about Russia’s war in Ukraine. I doubt that pundits in either camp can coherently describe what winning or losing a war means or looks like. So, in this episode, I will once again lean heavily on Carl von Clausewitz to describe w
Beyond IHL: The Law of Neutrality
Beyond IHL: The Law of Neutrality Apr 7, 2026 804 I am not sure, but I think that I mention the Laws and Customs of War in about half of my episodes. (Clausewitz, of course features in almost EVERY episode -- except this one.) There is one part of the Law of War that is infrequently discussed. So infrequent that the term International Humanitarian Law (IHL) doesn’t even include it. The International Committee of the Red Cross even says that it is
When the Law of War Fails (E132)
When the Law of War Fails (E132) Mar 29, 2026 665 I believe that the Law of War remains valid in modern warfare and is essential to establishing peace after war. Despite that belief we see States such as Russia and Iran and non-state groups such as Hamas operate in a manner that looks like violating the most fundamental aspects of the law of war, including deliberate targeting of civilians, to be an objective rather than a restriction. In this ep
