Ep 135Winning and Losing (E134)
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 what has always been true about winning a war and how that applies to current wars. For the pro-Sun Tzu crowd, stay with me to the end as he makes a rare appearance in my podcasts.

Ep 134Beyond IHL: The Law of Neutrality
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 of little importance! That nearly forgotten part of the Law of War is the Law of Neutrality. I do not agree with the comment in the ICRC’s IHL database tha, “the traditional law of neutrality has lost much of its former importance.” I believe that the armed conflicts between Russia and Ukraine and those in the middle east reveal problems which result when the law of neutrality is forgotten or abused. I believe these conflicts also represent an opportunity to reassert that branch of the Law of War, but only if States and nations have the courage to do so.

Ep 133When the Law of War Fails (E132)
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 episode of the Ancient Art of Modern Warfare I propose some reasons for this and insist that, in the end, it will be counterproductive to achieving success.

Ep 132Operation Epic Fury vs. The Powell Doctrine (E131)
In podcast episode 128, posted just before Operation Epic Fury began, I outlined how I think that an attack on Iran could be just, necessary, and what I perceived as a path to achieve the goals expressed by the U.S. Government in the weeks leading to the start of the war. I did not expect this to be a blueprint for what would actually happen. What I really did not expect was for the conduct of the war to be completely different that that. So different that more than the usual naysayers are questioning whether this war is just at all, or winnable. In this episode I go beyond the Just War Theory I used in my previous analysis, using the Weinberger-Powell model for the use of military force. This model is credited with successful use of American military force in the last decade and a half of the 20th century. Although it is not, and was never intended as a recipe for success, abandoning its thought process seems to have been a formula for failure. As usual, the opinions in these podcasts are my own and do not necessarily represent the opinion of the Department of Defense, anyone else in the U.S. Government, or any other organization I am or ever have been associated with. The United States should not commit forces to combat unless the vital national interests of the United States or its allies are involved. Dedication to my sons, 1st Lt Miles Mayer USAF and PFC Charles Mayer USA. With the commitment to our future military engagements being jus ad bellum and jus in bello. The Weinberger-Powell Doctrine (1984) Promulgated by Secretary of Defense Casper Weinberger. Believed to have been written by then Maj Gen Colin Powell, his senior military assistant. The United States should not commit forces to combat unless the vital national interests of the United States or its allies are involved. S. troops should only be committed wholeheartedly and with the clear intention of winning. Otherwise, troops should not be committed. U.S. combat troops should be committed only with clearly defined political and military objectives and with the capacity to accomplish those objectives. The relationship between the objectives and the size and composition of the forces committed should be continually reassessed and adjusted if necessary. U.S. troops should not be committed to battle without a "reasonable assurance" of the support of U.S. public opinion and Congress. The commitment of U.S. troops should be considered only as a last resort. General Colin Powell’s re-statement of the Doctrine in 1992, as Chairman of the Joint Chiefs of Staff. Is a vital national security interest threatened? Do we have a clear attainable objective? Have the risks and costs been fully and frankly analyzed? Have all other nonviolent policy means been fully exhausted? Is there a plausible exit strategy to avoid endless entanglement? Have the consequences of our action been fully considered? Is the action supported by the American people? Do we have genuine broad international support? If after careful consideration of these questions, the decision is made to commit U.S. military forces, then two imperatives shall apply: Clear and unambiguous objectives must be given to the armed forces. These objectives must be firmly linked with the political objectives. When we do use it, we should not be equivocal: we should win and win decisively.

Ep 131Revisiting Just Cause (E130)
In the last episode, I said that I would compare we know about Operation Epic Fury against the Weinberger-Powell doctrine for the use of American military force. I need to push that off for a week. Current events – and some pushback from my previous episode – require me to revisit my assessment of Just Cause in our attacking Iran. I stand by my initial assessment in Episode 128, which I recorded before our attack. In that episode I expressed my opinion that Humanitarian Intervention was a valid argument for both Just Cause and Last Resort. Nonetheless, I included a caveat from that episode where I said that the reality of a military operation against Iran would probably look different than what I proposed. It has, and so a review is important.

Ep 130The Persian Problem in Practice
I keep on trying to podcast about other things and current events keep distracting me. In my previous episode in this series, “The Persian Problem, I described some conditions under which U.S. military action against Iran would meet the Jus Ad Bellum criteria of Just War Theory. That description was, at the time I posted it, theoretical. Now we have the reality of having initiated combat operations. In this episode, I will review what I said in the previous episode and compare it to what we can see so far in this current conflict. Music: Holst, G.

Ep 129The Persian Problem (E128)
By the time anyone reads or listens to this podcast, the situation with Iran may be completely different than when I write this. In keeping with the intent of this podcast series, however, I thought it might be worthwhile to explore the possibility of intervention in Iran in a way that is in line with the enduring principles of war. In doing this I am not advocating such an intervention. Neither do I express any opinion about whether or not it is even a good idea. My intent is to frame a possible military intervention within the framework of time proven successful strategy and Just War criteria. Given the record of U.S. military interventions following the first Gulf War, I am confident that whatever we do regarding Iran will completely ignore that framework.

Ep 128The Morality of Strategic Bombing (E127)
Can strategic bombing of cities ever be justified? In the previous episode of this podcast series (E126), Col. Altieri said that the air force always considers itself revolutionary. Before I began recording, he cited strategic bombing in World War Two as both revolutionary and consistent with Clausewitz’s concept of making things so painful that the enemy will not continue to resist. I responded, saying that strategic bombing of the civilian population was a war crime and violates Just War criteria. Afterwards, I thought my response might have been hasty. In this episode, I re-look the idea of strategic bombardment, not as we might see it today, but as it was believed during WWII. In any examination of history, we need to see things as they were understood by those making decisions at that time, not from our current perspective. Music: Holst, G.

Ep 127A Revolution in Military Affairs? (E126)
The philosopher of war, Carl von Clausewitz, described three legs that support the architecture of war: Primordial violence, the play of chance, and reason. Clausewitz aligned the element of chance the military. Every revolution brings unintended consequences -- the free play of chance. A revolution in military affairs, therefore, means exponential chance to affect the other legs of that trinity. Did the predicted revolution in military affairs come about? Are we at the threshold of one? Is that a good thing or an unacceptable risk that must be avoided? Can we avoid it? Colonels Jayson Altieri and Robert Waring, US Army Retired and instructors in our War Colleges, join me to discuss some of these questions. This is longer than my recent podcasts, but I think it will be worth your time. Music: Liszt, F., and the USMC Band, Les Preludes. Public Domain Beatles, Revolution (1968).

Ep 126Predicting the future...has a rather bad track record (E125)
The inevitable never happens. It is the unexpected always. -- J.M. Keynes 1938 Almost everyone plays with predicting the future. Persons who speak with presumed authority and say that some outlandish thing is inevitable often get a lot of media attention. The more media attention, the more people come to think that the outlandish thing really is inevitable. In warfare, I have lived through the inevitability of guerilla warfare as the model for all future warfare; the inevitable demise armored warfare, the transformation of maneuver warfare; counter-insurgency warfare as the inevitable future war form; and more recently, that drones will so dominate the battlefield, that all previous forms of warfighting will be obsolete. In my opinion, inevitability has a rather bad track record. From time to time in these podcasts, I will revisit some of these predictions and see which of these were inevitable and which were overcome by reality.

Ep 125Greenland (E124)
The idea that we would invade Greenland is about the stupidest idea I ever heard. I find it difficult to believe that anyone believed that implying the United States might use military force was anything other than a negotiating tactic. An ill-advised negotiating tactic, but still, nothing more than that. Putting aside the fear and anger generated from different sources there are concerns and questions to be addressed, particularly as Greenland continues to move on its path to independence from Denmark.

Ep 124Disobedience to superior orders? (E123)
Recently, there has been controversy over public statements from some politicians about the responsibility of members of the armed forces to disobey unlawful orders. In theory, there should be nothing objectionable about that. Members of the armed forces, from the lowest enlisted to the highest general or admiral, receive regular instruction on the laws and customs of war and our responsibilities under the Constitution. In this episode, I describe what that means and where the responsibility to promptly and effectively execute orders ends.

Ep 123That Ancient Art of Modern Terrorism Part 6: State Sponsored Terrorism (E122)
This series on Terrorism is wrapping up with the problem of state sponsored terrorism. This form of international terrorism is most clearly a method of warfare, with the state using terrorist organizations as deniable proxies in armed conflict. International law, however, does not recognize that form of terrorism as war, but as criminal acts subject only criminal jurisprudence. This situation does little to stop this war form or to protect those who should be protected under the laws and customs of war.

Ep 122Counter-terrorism In Practice (E121)
In the last few episodes, I explained that international terrorism can be considered a war form and how it has been practiced through history. I described that, according to international law, terrorism is a crime and should be addressed as such. I also described how criminal laws are frequently inadequate to deal with terrorism used as a form of warfare. This leads to the question of how states deal with this in practice.

Ep 121Combatting International Terrorism (E120),
If terrorism, unlawfully attacking civilian targets to achieve a political outcome, is a modern war form, a different manner of armed conflict. When terrorist attacks are planned, organized, and operate from a foreign country, or otherwise use that country as a safe haven, what are the options of the attacked State in using military force to fight this new form of armed conflict? This episode of the Ancient Art of Modern Warfare looks at the authority and limitations of the war making powers of a state to do that. In this episode, I do not look at the right or wrong of any particular State or any particular operation. This episode only sets the context for the potential use of military force against international terrorist organizations.

Ep 120Terrorism and War (E119)
I decided to change the trajectory of this series. Rather than continue with the history of terrorism, I am jumping ahead to how terrorism fits within the overarching philosophy of war. The manifestation of terrorism as it has evolved in the past century is not inconsistent with our understanding of war. Understanding that will help us to understand the ways and means to defeat it.

Ep 119Is Terrorism Ancient or a Modern Development? (E118)
This continues my description of terrorism and warfare. The previous episode defined terrorism. This episode traces terroristic attacks from the Bible to the First World War and how it differed from modern terrorism. World War One had profound impacts on almost every aspects of human civilization and this included the use of terror to achieve political ends.
