The US vs. Iran: What Are the Options?
The video above, from PBS News, covers the alternative scenarios the current US-Iran War. They missed one Scenario. Can you guess what it is?
In this post, I'll summarize the video and then identify the missing scenario that I have covered in another post. Summary:

Nuclear War Simulation: Israel vs. Iran
Among many confusing justifications for the US attacking Iran is the threat of Nuclear War. President Trump has made it repeatedly clear that "Iran Cannot Have a Nuclear Weapon". This rationale for War is based on the assumption that the US has some fundamental interest in a Middle East War. Aside from the disruption of Oil Supplies (which is already happening as a result of War), what would be the consequences for the US of a Nuclear War in the Middle East? This post explores that question.
The computer simulation in the video above maps out what might happen in the Middle East.

What's the Difference Between Liberalism and Neoliberalism?
Notes
ChatGPT
Feature | Liberalism | Neoliberalism |

Primary goal | Broad individual freedom | Market efficiency & competition |
View of the state | Limited but essential for rights | Minimal, facilitator of markets |
Markets | Useful but not absolute | Central organizing principle |
Social policy | Some support for welfare | Shrink welfare; use market mechanisms |
Freedom | Civil and political freedom | Freedom as market choice |
Attitude toward inequality | Liberties more important, but some thinkers favor moderation | Often accepts inequality as necessary |

The State of the Union Address (SOTU)
February 24, 2026 President Donald Trump gave the State of the Union (SOTU) address for the first time in his Second Term. It was awful. In Google AI's summary:
This is not to say that Modern SOTUs have been much better.
From the standpoint of Systems Theory, the state of a system has many meanings depending on the system being studied. In Political Science, the "State" is the geographic area controlled by a central government--a non-variable. In Systems Theory, I like the following definition better:
The State of a system is the minimal collection of independent variables that explain the past and future path of the system.
As a place to start defining the State of the Union, I asked chatGPT to describe what topics should be included in the SOTU:
It is too much to expect that any President would be able to address all the topics above and the ones omitted are most likely the ones where the Administration is failing!
My proposal would be for some entity outside of government to take each of the chatGPT topics separately, and focus on defining and reporting on the state of each subsystem (Economic, National Security, Domestic Policy, Democracy-Governance, and Social Issues) and then forecast the state variables for the Future Vision. The graphic above does this for US1, a summary Economic-Environmental state variable from the USL20 Model (see the full description here and in the Notes below).
Notice that there are alternative futures based on alternative Geopolitical Alignments. Business-as-Usual (BAU) with the US continuing as the World Hegemonic leader produce unending exponential growth. Again, using Google AI:
Since the Trump II Administration seems to be stepping away from the Rules-Based World Order (RBO) there should be a democratic debate about the Trump II Administration's unilateral change in US Geopolitical Alignments. Instead, it is presented as a one-line "America First" slogan in the SOTU without prior Congressional debate or public input.
For example, the forecast above shows that Geopolitical Alignment with the World System (W) would produce a Steady-State Economy in the US after 2050. Given the Environmental consequences (if not complete impossibility) of unending exponential growth, the more reasonable idea of Limits to Growth should be debated with wide-spread public input. It is a Future Vision for the US and the World System!
I future posts, I will take each of the SOTU topics and develop a Measurement Model for each that allows the state variables to be forecast. The Measurement Model for the USL20 model is presented below and it should be scaled back to provide a reasonable SOTU Economy Index.
P.S. The Trump II Administration may actually be taking the US on a Random Walk, in which case the future is unpredictable.
Notes
You can run the R-code for the USL20 Model here.
USL20 Measurement Model
There are three component state variables in the USL20 model explain 90% of the variation in the indicator variables: US1 = (Growth - X - DPR - EPR - Q.OIL - O.BANKS - CAPU).
